Sally puts Bobut on a no-pudding diet and his usual antics ensue. The family gets hyped up when Spit's pet, Varch, a Harnazian Funazz, comes to live with the family. Varch takes an instant liking to Heather, who can't stand him. To make matters worse, Heather's new boyfriend, Ethan, comes to visit, and Varch welcomes him by eating the boy. But Heather feels bad when she finds Varch asleep in her closet and throws a shoe at him – but he doesn't wake up. Heather thinks Varch is dead, but doesn't realize his breed sheds their exoskin.

Snizzy invents a duplicating machine that makes things nicer. When Bobut insists on acquiring a Stinky Stevie doll (""the doll that barfs on you"") that his parents won't let him have, he clones himself and the real Bobut sneaks off to the toy factory. Doug and Cookie fear that they've done something wrong to make cloned Bobut so insipidly sweet -- while the real Bobut finds himself being packed and shipped to two obnoxious rich children.

Two of The Elders of the Neurtron Galactic Federation, the supreme beings who rule over the destinies of the alien Brody family members, pay a visit to see how future leader Bobut is being raised. Bobut quickly becomes disillusioned with High Elder Prissy's training methods (and the heavy crown he has to wear), so it's up to Doug to prove to Sissy that Bobut is being properly educated. Meanwhile, Heather goes out of her way to impress a clique of popular girls by having Spit gross them out.

Sally tries unsuccessfully to teach Bobut his ABC's. Cookie's in a conundrum when she meets Doug's boss's wife, Holly, and realizes that she once abducted Holly and dissected her brain. Doug tries to use the information to his advantage, which backfires when Holly announces she's getting a divorce. Snizzie creates a breed of mutant Yuccles, a candy that she loves. The puppet candies that call her ""Mommy"" are at first a burden, but they soon attack the school bully and finally move out and get their own TV show -- which bears a strong resemblance to ""Friends.""

While Doug makes plans to have a ""Brody Family Vacation,"" Sally daydreams about spending her time off having romantic dinners with a handsome exotic man. In preparation, Sally offers to have Bobut's passport photo taken by a happy clown. . .but the clown's happiness turns to despair when Bobut attacks him. Meanwhile, Spit invents a fake alien holiday as an excuse to get out of his schoolwork. But when little Bobut overhears Spit telling his siblings about it, Bobut expects a Tweeznax celebration.
