Get ready for thrilling action and adventure with Jurassic World! The Deep-Dive Submarine is bathtub safe with lights only. Push once for light ON, push again for light effect. There is space inside for two articulated 3.75-inch figures (sold separately). Fill the side tanks and base with air or water when filled with water the tanks and base act as ballasts and can sink down for underwater exploration. When traveling under water kids can use the articulated arm pincers to pick up objects. The sub fits on the rig for transport, too!
