Hey guys I just found something in Treetop Trouble that may or may not be a skip. This worked for two player, maybe it could be done in one player as well. During the first segment of the stage when you are inside the horizontal tree trunk, if one of the players dies and the other player revives him just as the dying player is about to hit the ceiling, both players get warped above the ceiling and can walk on top of the tree trunk. It is possible to get to the end of this segment like this. The only thing that has to be avoided are the big birds as their hitbox spreads above the holes from which they attack you. This also might be possible in other levels, I haven't tested it.
