- Grandpa shark is the first shark you can get. He isn't automatic and you have to ask him to do everything - Grandma Shark is a bit better. But only because she makes you cookies - Mommy Shark is better than grandma shark, but only because she is younger and is better at catching fish - Daddy shark is only better than mommy shark because he has a stronger bite. - Baby shark is the best because baby shark is so adorable that other animals underestimate her.
