I'm blue and hard with one strong muscle
To get me off a rock is a tussle.
Winter is a grind each year
Because I have ties that bind me here.
When my friends leave, you'll find
I always have to stay behind.
My shell is round and green.
Hiding in seaweed is my scene.
I can protect myself with claws raised high,
But I'd rather just sit in a tidepool
'till you pass by.
You have two feet. I have one.
So you may think I can't have any fun.
But we mollusks sure can slide.
We glide down slime trails into the tide.
I glue my shell to rocks and stuff.
Try to pull me off if you think you're tough.
But beware, even a mighty heave-ho
Won't pull me out of my volcano!
