How do you get the pet pet food for bubbles in pet pet park

you go to drako in Laughing springs so you go left and up and there he is. Then you ask him what he feeds Dug then he gives you a giant fish flake. Then you have to go to Jiggybug Lagoon and go to the bottom left part and ask "Kraygen the great" and ask him to crush the flake and then you return to Bubbles and give it to her.
