To celebrate half day (which resulted from his parents idiotically mistaking him getting home early from school because it was only a half of a school day as an actual holiday), Timmy wishes for a machine that allows things to merge with other items to become half-human and half-object. When Crocker gets a hold of it, he accidentally merges himself with cheese, and he uses this power to capture Timmy's fairies.

When Mark Chang celebrates his one-year anniversary on Earth, they go back to Yugopatamia and Mandie marries him and became queen while Mark's dad turns into Timmy and goes to Earth. Later, Mandie becomes a dictator, so Timmy and Mark must stop her before she destroys the Earth. Also, Timmy's Dad locked Timmy up in a cage made of wood because of what Mark's dad did as Timmy.
