Going somewhere?

I wonder if this fella would have a leg to spare?
I could do with a replacement.
Isn't nature terribly unfair?
We have only two legs, horses and dogs and cats have four, and these little guys have....... well......... lots. 
Too many to count, and probably more than they need.
And........ bloody starfish can grow their legs back.
I think we drew the short straw.
