Block sets with a sea creature theme, available in two types: 31 pieces and 33 pieces. These are the number 6 shrimp and the number 10 stingray. It seems that if you collect all 12 types, you can make a Megalodon. They're cute, and my children are collecting them, so I bought them. - Set Contents: 31-piece sea creature blocks - Set Contents: 33-piece sea creature blocks - Target age: 6 years and older Thank you for looking.
