Rambi Rumble
It's on the other side of Rambi's room (which is a short distance
past the continue barrel). It is very difficult to collect it
if you are Rambi. Jump up in front of the entrance to Rambi's
room to catch an invisible hook. Jump up and right to go over
the room to collect the coin.
Proceed from the entry point until you see a lone banana banana
up and left. Jump up at the banana to reach an invisible hook.
Jump up from there to the door.
Just before end of level. Use Rambi's "A"-charge to
smash through the wall under a barrel cannon.
