Tick Tock was a practice pet given to Peanut, Butter and Jelly by Ernest and Opal Otter in "Bubbles' Beginnings." An alarm clock, PB&J had to pretend to do things such as take it for a walk or feed it whenever it rang. By taking good care of it, they were able to prove to their parents that they were ready to care for a real pet of their own. Initially, they called it "clock," but Jelly decided that giving it a name would help them to think of it as a real pet. They sang the song "Little Friend" about all of the ways they would take care of it.
