It's Madame Foster's birthday! But when Frankie tries to take a simple trip to the mall, Bloo and the Gang tag along and are this caregiver's worst nightmare.

"The Trouble with Scribbles". There is one door in Foster's that is never, ever to be opened. Well, that's too tempting for Bloo and the house is soon infested with something unimaginable. Or something overly imagined.

When Bloo breaks Madame Foster's bust, it's up to the Gang to put it back together before rule-crazy Mr. Herriman finds out.
