- It is unknown what the two bird houses attached to the evil lair are for, it's possible they're Bird Brain's dwellings.
- Bird Brain's lair conforms with the archetype of supervillain lairs being located at high elevations (i.e. mountains, hills, plateaus).
- The house number for the lair is 80085. If looked at closely, it can look like it says "BOOBS". It was most likely intentional to make a call on Bird Brain's species.
- It is unknown if Bird Brain and Zippy have a new home, since it hasn't appeared since Booby Trap.
- Bird Brain has a cactus garden which he fell on in Mom-A-Geddon.
- Bird Brain's monster fell off of here in Booby Trap.
