Bimbette Skunk. She only appears for a brief few seconds to serve as the catalyst that pushes Fifi past her Rage Breaking Point with Johnny, but going off most Fanon, you'd swear she was a major character in the show. .
The insane hitchhiker who attacks Plucky in the car. On one of the regular episodes (a music video collection featuring a take on "Yakkity Yak"), he was also an escaped convict who hides out in the laundromat while Plucky is cleaning clothes.
The Woobie: Babs and Buster, because they spent their entire summer vacation floating down the river and were nearly eaten multiple times.
Fifi la Fume, although her epic rant at Johnny Pew almost cancels it out.
And Plucky. Dear Lord in heaven, Plucky. All he wants to do is go to Happy World Land, so Hamton's family takes him along. Little does Plucky know he is in for a road trip from hell. Hamton's family:
Brings their own food to a drive-in; Dad cuts Plucky off when he tries to order anything.
Leaves Plucky alone in a hot car while they sterilize a gas station restroom, with Plucky almost dying of thirst. By the time Plucky gets to a fountain, they're ready to leave.
Speaking of the hot car, Hamton's father won't use air conditioning because it wastes gas, but Hamton's mom won't let anybody roll down their windows either, because "People would think we can't afford air conditioning!"
Later, the clueless parents pick up a psychotic hitchhiker who is obsessed with pork/duck meat. How they make it to Happy World Land alive is a mystery for the ages, but let us not forget the coup de grace:
Plucky and Hamton's family have finally reached Happy World Land, and Plucky is thrilled. Yet the gang takes one ride on the parking lot monorail, turns around, and goes straight home, using the excuse that they don't want to overdo it.
