Ghostly Grove
Under the platform with the [O]. Use Dixie's helicopter jump to
the left of the platform, and float under it.
To the right of [O] there are two blue Krunchas (musclebound
kremlings).
Throw a barrel to break open the wall right of the second Kruncha.
(The wall is marked with a lone banana.)
To the right of the chest with [N], climb the pair of ghost ropes
that very quickly appear and disappear. (Jump on the first rope
just as it appears, without hesitating jump up and right to the
second one, and without hesitating jump up and right to the barrel.)
