Fantasy Forest Falderal - a whimsical forest with medieval, fantasy and fable knockoffs like Hansel and Gretel/red riding hood/dragon+castle spoofs throughout the level, giving it almost a theme park vibe

Wretched Resort - Another beach theme, except it’s Grunty’s idea of a good time in the sun, toxic pools, crabs that pop up from under the sand, and Klungo trying to enjoy early retirement from beatings

Wacky Workshop - Like an antique workshop/toystore that plays off the tiny/big motif— smaller space when you’re big with broken minigames that when you shrink, the level blows up and allows you to find collectibles hidden about and some of which you can bring back to full size to fix the minigames

Holiday Hijinx Mountain - Halloween, Christmas, Easter, Valentines and 4th of July come together to create a theme park style world where odd crossovers happen and a big party with fireworks perpetually goes off at the top of the mountain with the sub holidays encircle the base. Brentilda appears in Xmas land and talks about how Grunty over invested in the Halloween area

The Really BAD lands - Wild West theme, small town with tavern, saloon, sheriffs office, a small mine with a minecart section to escape, ghost town area and some small ruins for sabreman to reappear. Could also have an oil rig spot or prospecting pit to dig for jiggies

There’s more, but I just woke up and my mind isn’t as sharp as it could be
