Lets see, in Ghostly Grove, theres a pit somewhere in the level that you need to go down and fly left in with Dixie Kong.
In Bramble Blast, I think its near the end, where you bounce off the Flitters (Dragonflies), theres a barrel there that will blast you upward.
Yes, I know its vague.
P.S., try using Youtube.com, I remember seeing a guy get everything in the game there.
