Oh yeah I never did choose huh. Well i have my choices now....
1. Space Mama's Crater - shocker huh? I really love the rainbow background that's on the PS1 version, plus my favorite track from this world plays here
2. Eat at Joe's - One of my favorite characters in the original, Joe, resides here and while the firefly segment was challenging I still managed. The plot here is clear, restoring electricity, and once you're done you ride balloons to your destination after coming back. Plus it has the unique ability of returning to the starting phase as its last phase.
3. Anguish Lagoon - Has Bzzit, i love that guy. Plus riding with him is a lot of fun.
So yeah these are my 3
