Young teenager Jack Sullivan and a group of friends live in a decked-out tree house, playing video games, eating candy, and fighting zombies in the aftermath of a monster apocalypse.
Quint's been captured, Rezzoch's on a rampage and Jack's got a wish: to put an end to all of this mayhem, once and for all.
Jack's vow to never trust another monster is put to the test. Quint, Dirk, and June look to acquire a little - well actually a lot - of weed killer.
Fed up with his friends' bickering, Jack hopes a quest to the mall will get the buds back on good terms - because this is getting annoying.
While the gang visits June's old house, Jack assumes it'll be a fun walk down memory lane. Never assume, Jack. Never assume.
Quint, Dirk, and June are pumped for their up-all-night zombie stakeout. But Jack's running late... and he's supposed to bring the snacks.
While Thrull trains Jack to go after monsters and zombies with a new attitude, Quint and Dirk dig through trash - and June follows a hunch.
Everyone leaps into action when an exhausted Quint discovers that his zom-b-gone torches are offline. Meanwhile, Dirk is forced to team up with Chef.
As Jack's anxiety about the future continues to grow, he and June share a moment atop a giant heap of garbage (it's nicer than it sounds).
Jack convinces June, Quint, and Dirk to go to an amusement park, where the friends quickly discover they aren't the only ones there.
Jack sets out to confront the Wretch, June gets on Quint's nerves, and Dirk learns of an unappetizing third test to become an honorary monster.
After Rezzoch pulls Jack into an alternate realm, bardle transports June, Quint,and Dirk in hopes they can save him before it's too late.
Feeling useless when it comes to the fine art of fighting monsters, Quint sets out to prove himself to his friends.
The gang makes a stunning discovery at a fire station, Jack falls head over heels for a video game, and June has an urge to communicate.
While exploring a graveyard, Jack and Quint get emotional - really emotional. Meanwhile, June and Dirk find they have a lot in common. Oh, the horror!
Feeling June, Quint, and Dirk need to stop working so hard, Jack convinces his pals to take part in an over-the-top tournament with the monsters.
Desperate for a reliable energy source, Jack, June, Quint, and Dirk head to the planetarium, where a generator awaits - along with something else.
