If the poop knife doesn’t work, this may be your next best bet.

What has thirteen hearts, but no other organs?

I don’t eat breakfast, I don’t have feet, But I love a tree stump to feast

I can be found in a science lab or in the Muppets

I am a colorful sphere of glass or stone Used in a game where I roll alone I can be held within your hand Or scattered across the floor or sand Though I may crack if I strike too hard I'm cherished in the playground yard
