True and Bartleby get more than they bargained for when they agree to castle-sit for the Rainbow King and watch Frookie while Grizelda's away.

After mishandling Zee's powerful Zingy Zapper, an increasingly bulky Bartleby can't seem to stop objects from sticking to him.

Grizelda is determined to win the kingdom's first Great Rainbow Rally. But her self-centered driving throws the rest of the racers off course.

It's up to True to rid the kingdom of a horrible smell when the Rainbow King goes away on family business and makes her "Queen for a Day."

Grizelda commands the Grizmos to build the most dazzling tower in the kingdom. But they use so many crystals that her castle starts to sink.

The kingdom's Little Helpers are so focused on doing small jobs for everyone that all the big things are falling through the cracks.

The Rainbow King needs True's help with something involving water and giant plants -- but his Face Bubble message keeps breaking up.

A message mouse leads Bartleby to the Black Tabby Dojo, where he'll train with the Kittynati to become a ninja and earn his Red Tabby belt.

Someone's been snatching up all the nummle berries in the Rainbow Kingdom. Good thing detectives True and Bartleby are on the case!
