Episode Title:Debtor Alive!/The Grade that Wouldn't Pass!.Episode Description:Debtor Alive!: When the monsters learn that Sqweep is a millionaire on earth, they begin to borrow from her allowance. When her financial planner Pip, who works for Epsilon-11 Allowance Management, comes to Earth to collect payment, they can't come up with money, so when Pip goes nuts and begins to repossess and sell their commodities for sale on the galactic marketplace (such as Link's gravity, Ginormica's focus, Dr. Cockroach's vocabulary, and Coverton's dignity), B.O.B. gives him "B.O.B. Bucks" to set everything right. When Pip accepts the B.O.B. Bucks as actual currency, he concedes all debts to be paid and leaves.
The Grade that Wouldn't Pass!: After Dr. Cockroach tampers with Sqweep's project for thinking an answer on there is incorrect, the alien receives a Zrob minus (the lowest possible grade in the galaxy). Guilt-ridden, Dr. Cockroach then traverses to the center of Earth to assist her in finding the correct answer in a science test.
