she also has some of Yakkity's impulsive genes. Professor Crazyhair (Scott McNeil): A scientist and teacher at Onion Falls High whose hair changes colour like a mood ring, hence his name. He lives in Yakkity's basement, where he built a laboratory. His egg salad recipe is very sought after by evil geniuses who wish to use it to take over the world. Penelope (Tabitha St. Germain): A robot who is Lemony's best friend and works as Professor Crazyhair's assistant but lacks any social skills or confidence. Whenever she's embarrassed, her face turns red and she squirts out fire fighting foams from her arms transforming into fire hoses, squirting everything around her. Rondo (Ian James Corlett): Lemony's (rugby) football playing brother who is a senior in junior high. He is one of Yakkity's main antagonists often competing for the spotlight. Keo's Dad (Michael Daingerfield): A pineapple who can be bossy and rude at many times, and Keo's father. The identity of his wife (Keo's birth mother) is unknown and never explored; it can be assumed that she either died or got divorced before the events of Yakkity Yak. He's only a disembodied pineapple head; as the only time he ever had a body with limbs was in "My Dad the Robot". Wanda Harper (Brenda Crichlow): a fairy who works as Onion Falls High's librarian.
