All,
I don't see anything on the forums with a post of this nature. Can we make a list of all of the locations that we know of for members to refer to? Here is what I have so far from another gamefaq guide.
Halloween Town - behind a small wall right next to the Vortex of Death and a purple capsule
Halloween Town - to the left of the ramp that leads to the small Halloween island
Halloween Town - facing the Hub center, it's on the ledge to the right of the Octopus building
Halloween Town - under the Octopus building
Endor - highest level, on an open stump in the middle of a platform bridge that flips over
Endor - looking at the woods from behind it (in open space) it would be one level lower than the location above this one
Farm - in the barn
Farm - on top of the silo
Desert - hidden between buildings by the race track start
Desert - floating in space off the land (may have been a bug)
Area behind Interior House - On top of the trees
Area behind Interior House - On the land bridge going to the mountain
