I am a Snake

I have no legs. I have no arms. (arms down close to body)
I can take off my skin. (pretend to pull off skin)
I wiggle my tongue. (wiggle tongue)
I'm very, very thin.(hands on ribs, slide them down)
I can open my mouth so wide. (open mouth)
And eat my dinner whole. (rub tummy)
I can curl up nice and tight, (squat down low)
Or stretch out like a pole.
