Grim uses his scythe to magically combine the dogs and create Billy's dream dog, who calls himself Wiggy Jiggy Jed. Although initially Billy and Jed are best friends, their relationship falls apart when Billy tells Jed to sleep outside. Jed uses the powers of Grim's trunk to build a giant machine to capture the beds of all people. Billy throws Jed a dish of primordial ooze and he dissolves. Scythe for Sale: To raise money to buy Sea-Critters (similar to Sea-Monkeys), Billy has a garage sale where he sells Grim's scythe to Irwin for less than two cents. With the great mystical strength and power of the scythe, Irwin hypnotizes Mandy and takes her on a romantic date.

Naturally terrified of seeing Jeff, Billy runs away and a wild car chase ensues. The eggs hatch, and Grim decides to refill Jeff's hourglass that represents his lifetime so he does not die and can continue to scare Billy. Irwin Gets a Clue: After seeing Billy, Mandy and Grim battling a strange creature, Irwin again feels rejected by Mandy. Hoss Delgado, spectral exterminator, appears to help Mandy destroy the monster. Delgado decides to have Irwin as his sidekick and train him to be "cool" to win Mandy's love. Irwin gets an attire like Delgado's, and attaches an egg beater to his right hand.

Duck!: After Grim has a nice dream, a nightmare escapes the back of his head in the shape of a supernatural, invisible duck that makes farting noises.

The duck repeats the strategy, following other citizens, including Irwin and Billy's dad, resulting in all of them going to jail too. The duck tries to annoy Mandy, but she remains imperturbable by its presence. The duck disappears and Principal Goodvibes is really angry, and he gives Mandy 75 days of detention. Aren't You Chupacabra to See Me?: After being utterly bored of watching the same movie 60 times in a row, Grim takes Billy and Mandy to "Underworld Video" where they rent "The Legend of Chupacabra".

Since Junior has never attempted to transform into inanimate objects he cannot stop running and cannot revert to his human form. Billy keeps running forever while he becomes a national sensation known as the "Fitness Lad". It is revealed that the story was just all a fabrication created by the narrator, who parodies The Twilight Zone.

After the commotion, Mandy and Grim go search for Billy, and they find themselves in a strange place with other tentacled creatures.

To save Christmas, Mandy and Grim go to stake the Head Vampire, Baron Von Ghoulish (Malcolm McDowell), while Billy remains with Mrs. Claus to look after her.

Billy finds holographic instructions to bake cookies, which he gives to the vampire Santa Claus, restoring him to normal.
