Norb wants to be left alone so he can put together his "Last Year's Model" model. Dag takes it personally, and storms out of the dam, and sets up a party in a tree with a bunch of friends. Norb eventually gets curious and tries to spy on the party, but his attempts keep getting foiled by Dag. At the end, Norb discovers there is no party, and Dag was just trying to get back at him for telling him to leave him alone.
Tropes:
- Exactly What It Says on the Tin: Norb's models "This Year's Model", "Next Year's Model", and "Last Year's Model" are just models of said phrases.
-
Fridge Logic: How was Norb able to build the first two models without Dag annoying him?
- Inflating Body Gag: Norb spies on Dag's party by inflating himself with helium.
- Leave Me Alone!: Norb's attitude.
- Noodle Incident: Dag admits that he once inflated himself with helium. Given his warning to Norb, it didn't go well for him once he opened his mouth.
- Shout-Out: The title is a reference to Three's Company.
- Sticky Situation: While Dag offers to glue Norb's model together, he accidentally squirts glue all over Norb. Dag manages to get the glue off Norb.... and a chunk of Norb's fur too.
- Unwanted Assistance: Norb doesn't want any help, thank you!
