The Granny Squirrel is not featured physically in the tournament's storyline. Instead, the existence of the squirrel is represented by the resulted and subsequent transformation of Orwen, one of the witches of Morva, transformed by Merlin's magic, during the siege at the Forbidden Mountains. She is reverted into her normal form, by the end of the battle, thanks to her sisters' magic.
