Still investigating the crashed spaceship in Danville Forest, Cavendish unleashes a giant alien by accident, which then goes around to run around in the forest, thrashing anything in its path. Milo, Zack and Melissa, who were at a nearby day activity camp, find Cavendish and help him retrieve the alien creature before it destroys the whole forest.
Tropes:
- All Animals Are Dogs: This giant alien might as well be the Octalian counterpart to Canis Major.
- Chekhov's Skill: Every skill Milo, Zack and Melissa learned earlier in the episode comes into play when they capture the alien at the activity camp.
- Human Popsicle: At the end of the episode, when trying to warn Milo that the Octalians are out to abduct him again, Cavendish gets frozen in a block of ice by accident.
- Overly Long Gag: A group of men set up a campsite in the clearing with the leader making an overly long speech on how they're going to dump toxic waste here and make loads of money. Then the giant alien barges through the campsite and destroys everything, including his hand (which he needs to sign the contract to legalize it), his leg (which he needs to carry the barrels of toxic waste up the hill), his other hand (which he needs to unscrew the tops of said barrels), and an RV. On top of that, the alien knocks over a barrel of fuel, which explodes onto a jeep, sending it flying and landing it on the leader. This gag gets repeated beat for beat with a group of men who want to turn the forest into a desert theme park, and then it's subverted with the mayor signing a protection law, who holds a similar speech, but the alien does not intervene this time.
