Mr. Westmore takes McKenzie to visit his childhood home (by "childhood" we mean one of the first shows he worked on and by "home" we mean the house wherein dwelled The Munsters).
It's the final episode before the two-part finale! The challenge: Create a monster based on a sterotypical family archtype. Evan and Jordan share strategies for their respective characters, Bully Older Brother and Spinster Aunt.
Mr. Westmore thought the Bully Older Brother was a bit too demonic, which prompted Evan to re-do his scupt. When he realizes that his paint job is just like an earlier one from this season, he re-does that, too.
