Wonder Pets!
Each episode follows a similar structure, with many hallmarks and repeated elements. As each episode begins, children are heard from off-screen, leaving school at the end of the day. They say goodbye to the classroom pets. The classroom is always decorated with student artwork and other items related to a given episode's particular storyline, featured animal, or geographic location. Once the classroom is empty, a pencil holder rattles to create the ringing of a phone.
