Toddlers may be used in addition to common sharks. An average young shark may be able to shock larger creatures by consuming little food, depending on the leader shark. AI governs the toddlers, who behave independently of the dominant shark. There are particular young sharks that enhance some of a top shark's characteristics. You can never use more than one baby shark at once. But you can use both a common juvenile shark and a rare shark, such as a lava cub or a big white shark, simultaneously.
