Flexo uses a unique rigid construction brick and flexible tendon that allows you to truly flex your imagination and create designs you never thought possible. 100% compatible with LEGO® and other major brick brands, its a whole new universe of possibilities! The Flexo Ocean Life range comprises five unique sea creatures, a Crab, Fish, Seahorse, Stingray, and Turtle, each with their own points of difference in terms of colour, building difficulty and playability. All are bendable, submersible and float on their own! Flexo Ocean Friend: Crab Crabs come in all shapes and sizes - from a few millimetres across to a leg-span of up to 4 metres! We think you'll agree that our Crab is just the right size - but be warned, its claws have a nip in them perfect for chasing away our Stingray! The Crab is building difficulty level 2 out of 5.
