Plot
SpongeBob and Patrick start their babysitting service, and take care of a mother's babies while she's gone. After successfully taking care of them, another more older woman asks for their babysitting services, and they accept.

They go inside and check out the baby, only to realize it's uglier than usual, unaware that the baby is actually extremely old. They take care of her in several ways, as she tries to escape. After putting her to bed, SpongeBob goes upstairs to prepare a bath for the "baby," where he realizes that the baby is actually 137 years old after looking at a birthday card.

Before he can go downstairs to tell Patrick, he had accidentally let Mary's mom out while he was spaced out. They panic and look for her at a sewing circle, while Mary's mom is doing several extreme activities.

They eventually find her, only for Mary's mom to hang them on some coral and punch them until they are unconscious. She falls asleep, and SpongeBob and Patrick put her in her wheelchair and walking toward the sunset.
