Which letter am I?

My alien has three legs that are swiggly like worms. She has rotten teeth becuse she has not got a tooth brush so her teeth stay grimy. Her mouth is purple. Her name is Alien Squiggle. She has ginormous eyes which are like a big frog. She does not have a body so her legs are on her head. She scuttles like a crab. Her head is pink and her eyes are blue. She's got a nose on the side of her head. So whitch letter am I?
