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

I swallow the unwary, but have no mouth. I hold you fast, but have no hands. The more you struggle, the deeper you sink. What am I?

I jingle and jangle on the cowboy’s boot, I’m small and shiny and kind of cute.
