The Mystery Dildo Size Upgrade
Full details
Ready to level up your dildo? For a small cost, transform your FREE X-Small mystery dildo into a bigger sensation. Because sometimes bigger really is better...
Look, we love our X-Small treasures, but if you're craving a bit more oomph in your adventures, this upgrade's got you covered.
Here's the deal: This upgrade swaps your automatic free X-Small for a bigger size of your choice. You still get ONE mystery dildo total (just a bigger one).
And before you ask: No, you can't buy this upgrade by itself. It only works if you have the free X-Small in your cart (which appears automatically when you add any toy). If you try to purchase it alone, our system will throw a tantrum and cancel your order. Nobody wants that.

I got the Dragon dildo in a cute blue metallic colourway. There was no card with the order to specify what kind of dildo it is.
I think it's super soft firmness, but I wish you gave some info about the free dildo, I'd love to know what firmness it is because I enjoy it and would like to buy the same firmness in the future.
This one is definitely going to take a little working up to. We upgraded the freebie to a medium and lord cthulhu himself appeared. It's extremely well made and well tapered but that knot is definitely going to require some patience.
Okay, I was so curious about this one and it did not disappoint. It's cute, it's squishy aaand it's a gorgeous color.
Very soft, but very good textures,this style needs to at least be a small for me personally, but it's a good one. I was very pleasantly surprised! Thank you, nice random choice!
Got a medium Goblin II as a mystery dildo (site photo for reference), and it was the most spectacular thing I didn't think I needed. *Almost* spooked by how well the mystery/upgrade thing has worked for me. Don't go changin'!
I got the dragon knot 2 in xs as a freebie with my purchase and I was happily surprised! I was expecting not to like it too much because its small and the tip looks pointy. The softness of the silicone means it doesn't feel pointy at all and its a bit smaller than I would like but I still love it cause its great for warming up and for double penetration with fingers or other toys. The texture is quite intense on this one wich I also love and the colour is gorgeous
Received the amazing, girthling treat of The Alien, for this earthling!
Absolutely love the option for a fun surprise of the right size, with the upgrade option. A lucky dip that just keeps giving!
When there was a small issue with my order, Uncover Creations bent over backwards to ensure this little extraterrestrial was able to arrive on time for a little intergalactic probing. 10/10
Treat yourself!
Got an upgrade to small for the free toy and got werewolf. Not sure what happened to the sizes 😆 but it's bigger that my dragon knot I so keep it in mind. It's perfect though and the knot is manageable ❤️
My mystery was the Lily Bud (site photo included for reference), which I would never in a zillion years have chosen (although I did think it was cool to look at). I did, however, try it out — an instant fave! Truly the perfect gift: something wonderful that I'd never have got for myself. Great job, UC!
I ordered this lil' guy along with my first order for a mystery dildo (medium-size), and got this mystery one in x-tra small. All in all, I was happier with this free additon than the original order! It's a bit small for me to enjoy, but the shape is great- my partner also really enjoyed the knot- and I'm actually thinking on ordering a bigger size for myself with this same shape- The Werewolf. I also loved the colouring on it! It didn't suction but was a lot more stable, not too floppy, and had a nice feel to it.
I aimed for a mystery dildo, because why not make that my first order here? I knew I could get pretty much anything, and I know I like to challenge myself. So I ordered a medium. I know depending on the model, it can be a bit bigger or a bit smaller. Well, guess what- I ended up with one of the "Huge Dildos", The Capricorn. Even though I love the idea of the design, in that size it's just -not- practical, even if you would be able to get it inserted. It doesn't balance by itself, especially not in an upright position. It's too heavy to hold and move manually in your hand. The biggest insertable part is shaped (alongside the smaller part) in such a way that the angle is off, and you can't easily get it in either way, especially because it keeps falling over on itself. All in all, I liked the mystery, but it turned out not to be the best gamble for me. It wasn't just about my body not very easily allowing for the girth to be inserted- that's not an issue on Uncover Creations' part- but I think it could be a better-designed model for more fun.
Hi there
Thank you for taking the time to leave such a detailed review.
We're glad to hear that you enjoyed the mystery aspect of your order and went into it with an adventurous mindset! As this was a Mystery Toy purchase, the design you receive is based entirely on what is available in stock at the time your order is processed. This means customers can receive anything from smaller, more beginner-friendly designs to some of our larger and more challenging models, such as Capricorn.
We appreciate your feedback regarding the size, weight, and handling of the design. While many customers enjoy larger toys specifically for those characteristics, we understand that they won't suit everyone's preferences or anatomy.
The Mystery Toy option is intended to be a surprise and a bit of a gamble, which is part of the fun, but we completely understand that this particular design wasn't the best fit for you. Thank you again for your honest feedback and for giving our Mystery Toy option a try.
Kind regards
The Uncover Creations service team
Tentacle knot 2 -Medium, super soft - I was slightly disappointed when I opened the box, and saw it ( mystery upgrade ) , but this has surpassed my expectations completely. The proportions of the knot and position makes this a very effective indeed and quite addictive. I actually prefer this to the toy that I choose. Requires a little encouragement to get inside, but very controllable & the texture is amazing and it's a great addition to the collection 100% recommended.
My mystery dildo was actually missing from my order (first time that's happened from mutiple orders) but I let the team know and was was sent out to me no issue and really quickly thanks team. It's actually turned out to be one of my favourites!
I got this guy as a mystery and arrogantly upsized it to a medium. After actually looking at the possible mediums, I got worried that I'd get something much larger than I could take.
While it is pretty big, Im so happy with this mystery, I almost like it more than the grinder I initially bought.
First off, I LOVE that its a knot, I'm pretty sure its the EquiKnot. I've never had a knot, and I've really always wanted one. Can I take it? Absolutely not lol, but I still really love the look of it.
Its actually pretty soft and came in this beautiful bright yellow shimmer. I love the tapered head, its my favorite part. Its very girthy and its curve is just perfect.
I have received 3 with various orders. They have all been x-Small in size. They are fun teasers, to warm up for the main event.
I got three surprise dildos with my orders 😁
It's always so great to have free stuff, and it's even better when it's some great dildos!
I just wanna start out by saying I absolutely love the free mystery dildo promotion. It was definitely the reason why I’ve decided to hit pay both times I’ve ordered from UC. I paid for a size upgrade to small for the first mystery dildo I received and received this dragon knot in blue. Unfortunately the medium firmness made it uncomfortable to use and it was honestly still a bit small for me.
For my second UC order I received the light pink AND darker pink dildos as mysteries. The light pink was also a size upgrade to a small and holy wow the size difference between the small dragon knot and small tentacle is insane. Unfortunately the tentacle is actually a bit big for me but I still absolutely love it.
The unexpected extra small smaller tentacle is sooo fun though, I might even order it in a small or medium! I think the -1 star is just because a “small” is so unpredictable that paying extra for an upgrade definitely doesn’t guarantee that you’ll end up with something of a desirable size. Again though, LOVE this promotion and overall happy with my free mysteries.
The free mystery dildo has been the tipping point in hitting that “checkout” button not once but twice for me. I love fantasy dildos but the price has just been too steep for me to order from BD or other fantasy dildo sellers.
The first mystery dildo I received (the Dragon Knot in blue, small size upgrade) was medium firmness which unfortunately didn’t feel great as it was too firm for me. On my second order I explained that a medium firmness hurts and asked if they could please make it super soft. I received not one, but TWO gorgeous tentacle dildos in super soft. The larger of the two was a size upgrade to small (that’s a small?!) and the smaller of the two was a surprise double bonus? I also ordered a vacu-lock suction cup for my dildo so maybe that’s what the double freebie was about. They also send me this adorable micro dildo.
Insane to me that everything pictured was from purchasing just two dildos! I am officially a loyal UC customer!
The texture is just.... Perfectly smooth, firm is the perfect description and it feels amazing
