Marcel the Shell with Shoes On

I am helping my friend with a book publishing project and spent some time working on it today. I went to visit her and asked if there was something special she'd like for the cover image and she said "Marcel the Shell with Shoes On" and I said, what? She proceeded to tell me about the book she shared with her little granddaughter years ago, who this book I'm working on is for, and pointed to her mantel where I found the little Marcel above. Now I need to find this for my little twin bunnies.
