Crab Cake

Under the sea, fish do what fish do: Seahorse hides, Pufferfish puffs up, Parrotfish crunches coral, and Crab . . . bakes cakes?
Scallop swims, Dolphin blows bubbles, and . . . Crab bakes cakes.
And so life goes on, until one night when everything changes with a splash!
In the face of total disaster, can Crab's small, brave act help the community come together and carry on?
