“The main model offers the biggest collection of animals, including a sea turtle, crab, jellyfish, seahorse and a couple of additional fish (species on the back of a postcard, please). They’re all positioned on a slice of seabed decorated with deep-sea fauna, and it’s that... More display that can be hooked together with the two alternate builds for an expansive collection of underwater animals.”

Boys and girls aged 8+ can build, play with and display this colorful LEGO® Creator Sea Animals (31158) 3in1 building set. It features 2 fish, a turtle, a jellyfish and a seahorse toy displayed on transparent rods as part of a seafloor stand adorned with sea plants, plus a red crab figure. The sea creature toys can swap positions on the stand, which can be straightened or angled.

LEGO fans can choose from 3 different buildable underwater scenes with this 3in1 toy playset. They can build a collection of 6 sea animals with a seafloor stand, rebuild it into an octopus and squid next to a bubbling piece of volcanic rock, or 2 fish gliding around colorful sea plants.

LEGO Creator 3in1 toys make great gifts for kids, with 3 different models to
create in every box. Kids will be excited to build, rebuild and build again. The same set can be purchased 3 times so kids can enjoy bigger adventures and connect and play with all 3 models at the same time.
