## Description

Explore the depths of the ocean with the LEGO Creator 3in1 31090 Underwater Robot, featuring highly posable joints, large transparent domed helmet, red robot eye, ballast tanks and huge feet for exploring the seabed. Remove the robot eye to transform the dome into a cockpit control center. The Underwater Robot also has a claw and drill at the end of its left arm and a grabber on its right. This set also includes a manta ray figure with a spiked tail, plus a small seabed build with gold nuggets and a sea plant. With LEGO Creator 3in1 sets you get 3 different build and play experiences. Build the Underwater Robot and then rebuild it to create a Submarine or an Underwater Crane treasure hunt center for more deep-sea action and adventure.

Review: Pick Which Creation to Build Out of 3 Choices. - This is a nice build. It didn't take long to build (½ hr, give/take). I got this for my son when he was 10. The 3 in 1 sets are great because my kids can decide which of the 3 things they want to build. Now these sets share the pieces for all 3 different builds, so that means that all 3 things can NOT be built at the same time. The creation/build has to be taken apart and then simply follow the directions to build something else using the same blocks. Not all 3 builds will use all of the blocks, so there will be spare pieces. Legos are always fun and it keeps my kids occupied for a little while and gives them something fun (& creative) to do other than mindless TV. Overall this is another great set from Lego. We have a lot of Lego sets and we're usually very happy with them.
Review: My son loved it - Anything Lego my son loves. The fact that this was a 3-in-1 made building it all the much more fun for him.

## Questions & Answers

**Q: I’m guessing that, since this is lego, there are actually no metal parts and can be taken underwater. am i correct in assuming this?**
A: Great question! This set doesn't include any metal parts nor stickers. You can find more information on LEGO bricks in water here: LEGO.build/BricksWaterproof. - Luigi, LEGO® Customer Service

**Q: Ordered this item to gift before xmas! It was delivered to the wrong state. Who do I need to contact for this to be corrected?**
A: Hi there! We're sorry for the frustration. In cases like this, it is best to reach out to the seller directly to report the issue with your order. - Sonia, LEGO® Customer Service

**Q: Can this actually be played with under water?**
A: Hi there! Our bricks are A-Okay underwater as long keep in mind some basic care tips. For example, make sure to have them in plain water - water that has chemicals in it (like pools) might not be good for the bricks. You'll also want to make sure the water isn't too hot, as that can make the plastic change shape. Lastly, always dry your bricks with a cloth, or let them air dry. Don't put them in driers or dry them with heat. - Emily, LEGO® Customer Service

**Q: I’m guessing that, since this is lego, there are actually no metal parts and can be taken underwater. am i correct in assuming this?**
A: Hi there!

LEGO® bricks are A-Okay in plain water. You'll want to make sure that the water doesn't contain any harsh chemicals or cleaners, though (chlorinated pools, for example). And also make sure you let your bricks air-dry - no hot dryers as the temperature can make bricks change their shape. Lastly, while this set doesn't have stickers, if you want to use a set that does have them in water, it's a good idea to leave the stickers off.

Kind regards,

### ⭐⭐⭐⭐⭐ Awesome for kids and adults
*by M***W on December 27, 2019*

When I was a kid, Legos were things you assembled and reassembled into different objects. These days, most Legos are a set that gets put together once and left as is. I love that these show how to make three different objects with the same set. It it a great blend of Legos as they used to be with Lego sets as they are today.
