Milo soon grows attached to a stray Scottie dog the Oblongs take in, but the pet brings out the animal in the hyperactive boy, and the family gives the pooch away to Bob's boss, George, thinking he'll have a good home. But when his new owners soon tire of him, Scottie finds himself in an animal testing lab, sniffing perfume with narcoleptic side effects. So the Oblongs set out to rescue Scottie before it's too late.

Biff and Chip finally get their driver's license -- and end up smashing Bob's car. To make it up to their Dad, the male siblings chip in to buy a new car at an auction.
