In '100% Wolf,' a young teenage werewolf named Freddy Lupin comes from a long line of distinguished werewolves. But on his 14th birthday, Freddy's first transformation goes wrong, and he ends up being turned into a poodle instead of a fierce wolf. Now, Freddy must find a way to prove that he is 100% wolf and save his family from a mad scientist who wants to capture them for his evil experiments.

When Freddy Lupin's wayward wish transforms him into a werewolf and deposits a mischievous moon sprite on Earth, Freddy must restore the cosmic order before the earth and moon collide.
