Pretty Boy is one of the main characters in Teacher's Pet.
Pretty Boy is a bossy, big-mouthed canary with a Napoleon complex. He yells at everyone for everything. He loves seed bells and soaps. He also has a wonderful singing voice.
Pretty Boy is a canary with green feathers, and an orange beak.
Pretty Boy is featured in the subplots of the series along with Mr. Jolly, the pet cat, and they have adventures of their own. They mostly stay inside the house watching television and using Leonard's computer, however they did leave it twice during the series, first in "Saving Mr. Jolly" when they each thought they were each missing and in "Pet Project" when Leonard and Scott brought them to school for pet day. Additionally, in "The Grass Seed is Always Greener", Pretty Boy leaves the house separately and ventures into the wild, with Scott and Leonard scrambling to get him back.
In the movie, he stays at home with Spot and Jolly while Leonard and his mom are on vacation. After spot leaves to see Dr. Ivan Krank, he and Mr. Jolly cover for him.
Later, they find out that Dr. Krank turns animals into mutants and go to save Spot.
After getting lost in Cuba, they get to Florida by a garbage truck and find Leonard and they find out about what happened to Spot. Spot (who is now a man) arrives and they warn him that Leonard's gonna turn into a dog.
When they get to the lab, a battle and an explosion begins turning Krank into a mouse and Spot back to a dog.
Afterwards, they hid under the RV's beds to get home as part of Spot's plan.
