Meet Sylvester the Oyster. He has a lisp!

A lot of the sea creatures call him “Sylvester the Jester”. He’s cheery, funny, and sure to make you giggle!

Sylvester spends most of his time sitting in one place, but the other sea creatures come to visit him when they’re feeling blue. (Cecil seems to visit the most often…) They know he can cheer them right up!

They all appreciate Sylvester as a friend, and he loves making everyone happy!
