Sea Monster Review – Erotixxx Toys: a tentacled dildo with continuous stimulation

TL;DR

The Sea Monster by Erotixxx Toys is a dildo sculpted around a tentacled, textured, and slightly curved form. Tested here in size XL (75% Soft), it offers smooth insertion, with an offset head, evenly distributed texture, and a tentacled structure that delivers continuous stimulation with every movement.

Its surface features small regular bumps nestled in recessed areas, along with deep folds along the tentacles, creating a rich tactile experience without abrupt transitions. The 75% Soft firmness maintains flexibility while keeping the texture perceptible.

Accessible, stable, Vac-U-Hole compatible, and made from high-quality platinum silicone, the Sea Monster is ideal for those seeking sustained tactile sensations without chasing size-based challenges.

Where to buy the Sea Monster

A first encounter sparked by curiosity

While browsing Mr. Hankey’s Toys listings, I discovered a brand I hadn’t come across before: Erotixxx Toys. Seeing several of their models directly listed on the MHT website immediately caught my attention. In a market this fragmented, such cross-brand visibility is rare — and usually a sign of mutual respect between makers. Enough to make me want to learn more.

So I got in touch with Erotixxx Toys to propose an interview. The exchange was quick, direct, and professional. The interview was published shortly after on the site, and the idea of a product review followed naturally from there.

A limited request… that turned into much more

Following that conversation, the brand offered to let me test a few of their models. I suggested a more limited shipment, selecting just one dildo to begin with: the Sea Monster, whose design had really caught my eye.

But a few days later — surprise: a FedEx tracking email informed me of a package weighing over 9 kilos. Erotixxx Toys had ultimately decided to send me several models, without me requesting anything beyond the first — with a clear message: no fees on my end, they would handle everything.

A confident, professional gesture that set the tone right away. And so it’s with the Sea Monster — the toy I had originally chosen — that I continue this test series, following The End Zone and the Goblin King.

Simple packaging, thoughtfully done

When it comes to packaging, the brand sticks with a minimalist presentation: each toy is sealed in thick plastic wrap, with no box or pouch. It’s basic, but effective. Despite the size and weight, the package arrived in perfect condition.

A small Erotixxx Toys sticker adds a discreet bit of branding — subtle, but welcome.

That said, a dedicated storage pouch — made of fabric or non-stick material — would be a helpful addition. It keeps dust off and avoids unwanted contact with other toys during storage.

A sculpted design, made to explore at your own pace

The Sea Monster is a dildo with a bold, organic design, defined by undulating curves and volumetric contrast. As with other models from the brand, the toy can be approached in different ways depending on the chosen size and silicone firmness. Erotixxx Toys offers three firmness levels and four sizes, allowing users to tailor the experience to their preferences and physical comfort.

A gradual build-up without brutality

The Sea Monster comes in four sizes, with a progression that lets you adjust intensity without losing the essence of the design. Even though the dildo looks impressive, its difficulty curve is smooth and manageable.

• Small – A beginner-friendly option to explore the shape without pressure.
• Medium – Noticeable size increase, with a stronger physical presence once inserted.
• Large – A demanding format, best suited to users already familiar with size play.
• X Large – The largest version of the Sea Monster, reserved for advanced practice.

Each size includes a detailed size chart available on the product page — a helpful way to anticipate the toy’s ergonomics, with clear visuals and measurements in both cm and inches.

Three firmness levels for tailored sensations

The Sea Monster, like most dildos from the brand, is available in several silicone firmness levels. This choice directly affects how the toy behaves once in hand — or in body. Maneuverability, filling sensation, tactile response: everything shifts depending on firmness.

• 40% Soft – Very flexible, it follows your movement and smooths out the design’s texture.
• 75% Soft – Slightly firmer, still flexible: more precision without excessive resistance.
• Med Firm – For those who prefer stiffer toys, with more defined pressure against the walls.

As usual, European retailers generally offer only the softer versions (40% and 75%). To get a Sea Monster in Med Firm, you’ll need to order directly from the official Erotixxx Toys store.

Limited customization outside the official store

On Erotixxx Toys’ official website, the color range is extensive: classic flesh tones, vibrant colors, UV-reactive or metallic finishes, and glow-in-the-dark options. These can all be combined with your chosen size and firmness.

At resellers, the selection is more limited. Gaymegastore, for example, only offers the Sea Monster in Metallic Green, with no customization options.

If you want to configure your toy to match your preferences — size, firmness, color — you’ll need to order from the manufacturer’s site. Be aware this may involve higher shipping costs and potential import taxes, depending on your location.

An organic, tentacled, and lifelike design

Beneath its tentacled appearance, the Sea Monster reveals a thoughtful and structured design. Every fold, recess, and branch integrates into a cohesive whole, inspired by marine creatures.

A complex sculpture, between chaos and symmetry

The Sea Monster is built around a structure of three tentacles, with one main, longer one, around which two smaller ones coil. The result is an asymmetrical shape with clearly defined hollows between each branch, giving the dildo a sense of depth and presence, even when static.

This imbalance is enhanced by a partially flattened head covered in irregular folds, and by a base that hints at genital forms without slipping into realistic imitation. Altogether, it evokes a hybrid creature, somewhere between a tentacle, a mollusk, and an unknown organ.

The base is wide and flat, featuring a Vac-U-Hole and the brand’s website address embossed underneath. It’s completely red, in contrast to the more intricate gradients on the rest of the toy. The visual break is a bit stark — it adds clarity to the shape, but one might wonder whether a textured base in line with the rest of the design would have made it feel even more immersive.

A texture inspired by sea monsters

Like the Goblin King, the Sea Monster is covered in small circular bumps scattered across the surface. Here, they’re set into clean, regular hollows, reinforcing the toy’s marine-like aesthetic. The whole shape unmistakably recalls a creature from the abyss.

The main tentacles are marked by deep, angular folds that create bold texture and convey a sense of tension or movement. Every design element contributes to a strong, coherent visual identity rooted in aquatic and monstrous imagery.

The version received is in Red & Black, with beautiful transitions between dark and bright areas. The head and base are mostly red, while the tentacles display mixed hues, with streaks of red flowing into the deeper grooves. The finish is refined and immersive, true to the brand’s visual identity and well suited to a toy inspired by the deep sea.

Grip and sensations: a dildo that makes itself felt

The Sea Monster isn’t an extreme or highly technical toy, but it delivers real sensory intensity. Its irregular shape, textured surface, and subtle curve make it feel particularly alive once inside. It’s a dildo designed more for friction than depth, with sensations driven by continuous contact between silicone and skin.

An intuitive grip — as long as you lube well

The Sea Monster is easy to insert, but one thing is key: plenty of lubricant. With its intertwined tentacles and many grooves, you can’t just coat the surface and expect smooth sailing. You need to spread lube thoroughly across every zone, even the hidden spots. If not, some areas will stay dry and tug during use.

The slightly off-center head also changes the way you enter the toy. You tend to angle it slightly, which creates a noticeable curve as the dildo shifts during use. And this curve is very perceptible — the Sea Monster rubs along its entire shaft as it repositions, creating a deep and satisfying pressure.

The 75% Soft firmness offers a nice level of flexibility while still transmitting the toy’s surface details. It doesn’t fold in on itself, but it bends enough to follow movement, with just enough resistance to intensify contact.

A rich texture that does all the work

It’s really the texture that sets the Sea Monster apart. The small, evenly spaced bumps in their hollows, the folds along the tentacles, and the shifting shapes all create a dense sensation — continuous, but never monotonous. You can feel the dildo move, catch slightly in places, and glide with texture.

Once fully inserted, the base presses firmly against the body, and you can clearly feel the “testicles” pushing in. It’s a very satisfying point of contact, creating a sense of stability and full-body engagement — even without aiming for deep penetration.

I wouldn’t recommend starting cold with this model. Like any textured toy, a little warm-up helps you enjoy it more. That said, it remains very accessible. There’s no sharp ridge or tricky section to overcome, and the progression feels smooth throughout.

This toy is all about tactile richness, not brute force. And maybe that’s where a 2XL version could shine — for those who crave intense textures but also want a real challenge in terms of size, a larger format could take this design even further. As it stands, the Sea Monster is already a success — but it’s easy to imagine how much more it could offer at a bigger scale.

A toy that rewards mindful preparation

The Sea Monster isn’t difficult to use, but it’s not a grab-and-go toy either. Its irregular shape, detailed texture, and wide base all require a bit of forethought — both physical and practical. It’s not the kind of dildo you reach for on a whim: it’s best appreciated when approached with intention.

Cleaning and storage: the little things count

Like all quality silicone toys, the Sea Monster cleans easily — as long as you take your time. A wash with warm water and mild soap is enough for regular use. You can also use a toy cleaner, provided it’s silicone-safe.

Its many folds, creases, and grooves can hold onto lube or residue: it’s best to scrub textured areas by hand, or with a soft brush if needed.

Once dry, it’s best to avoid prolonged contact with other toys, especially those made of unstable materials (PVC, TPE, etc.). Erotixxx Toys doesn’t include a storage pouch, so I recommend using a breathable fabric bag, like cotton or linen. It protects from dust while preventing surface reactions.

Grip and lube: creating the right conditions

Even though it’s relatively easy to use, the Sea Monster deserves proper prep. It’s not extreme in size, but its pronounced texture and subtle curve benefit from some warm-up. Starting with a smoother or smaller toy at the beginning of a session often makes it easier to enjoy the relief without tensing up.

Using a water-based lubricant, in generous amounts, is essential. Make sure to work it into every crease of the toy, including those that aren’t immediately visible. Otherwise, some areas may stick or drag during use.

The slightly offset head might also require some adjustment during insertion: this isn’t a toy that always follows a straight line, so you may need to correct the angle slightly to match the curve.

Finally, the wide and stable base gives you confidence to press down — whether solo or on a flat surface. The Vac-U-Hole at the bottom also opens the door to harness or machine play, if compatible.

Sea Monster: a well-designed, accessible dildo with rich sensations

The Sea Monster isn’t a toy that tries to impress with size or intensity. Its strength lies in its balance: it’s relatively easy to handle, but delivers dense, varied sensations thanks to thoughtful texture and a shape that keeps your body moving.

The design is particularly successful: original without being gimmicky, expressive without unnecessary complexity. Every fold, every bump, every curve feels like it was crafted to serve both aesthetics and sensation. Visually, the two-tone color adds real depth to the overall form.

This is a toy that guides rather than overwhelms. It works on all levels — insertion, stimulation, anchoring — and even though it’s not technically challenging, it manages to fully fill the space, stimulate without excess, and offer a satisfying overall experience.

A solid choice for lovers of prominent textures who want a well-made, immersive toy that’s soft enough to adapt to different desires — while still offering a distinct personality.

Where to buy the Sea Monster?

The official Erotixxx Toys website offers the Sea Monster in all four sizes, with three silicone densities and a wide selection of colors, including two-tone, metallic, and UV-reactive finishes. It’s the best way to fully customize your toy — size, feel, and aesthetic.

On the European market, Gaymegastore carries the model in all sizes, but only in 75% Soft density and Metallic Green. A convenient option to avoid customs fees and get faster delivery, though without customization options.
