Answer:
I have a hundred legs, but cannot stand. I have a long neck, but no head. I cannot see. I'm neat and tidy as can be.
I am a precious little thing, dancing and eating all the time. Watch me from a distance, so you can feel my warm and gentle love. But don't come to close or my next meal you could be!
My first is in fish but no in snail. My second is in rabbit but no in tail. My third is in up but not in down. My fourth is in tiara but not in crown. My fifth is in tree you plainly see. My whole a food for you and me.
They made me a mouth, but didn't give me breath. Water gives me life, but the sun brings me death.
This thing all things devours: Birds, beasts, trees, flowers; Gnaws iron, bites steel; Grinds hard stones to meal; Slays king, ruins town, And beats high mountains down.
Special abilities and brightly colored underwear are all you need to be one of these.
