The unicorn Harry was the pet of an unknown resident whom dwelled near the outskirts of Festeron. Affection towards his owner was demonstrated through fond nudges with the horn and loving looks from gentle brown eyes.

When the Mad Arsonist of Festeron set Harry's barn ablaze, the unicorn was able to escape before being consumed. He was later soaked by a downpour when his owner wished for rain to fall to extinguish the terrifying inferno.
