One day, Mommy sends the kittens to take the garbage out and asks them not to forget to sort it. Daddy hears the conversation and promises that after the job is done, the kittens will get a delicious banana muffin. However, while dreaming of the muffin, the kittens completely forget about sorting the garbage. When the kittens come inside for the muffin and tell their parents they had to put the garbage in one container, Mommy and Daddy are upset.
