Pipsqueak is a white and brown earth pony colt. He goes to school with Sweetie Belle, Apple Bloom and Scootaloo, as well as being taught by Cheerilee. In both of his major appearances, Pip squeak has shown an interest in princesses: Luna in "Luna Eclipsed" and Twilight in "Twilight Time." He originally lived in Trottingham, but moved to Ponyville.
