Greetings. I've collected all the gold coins in every world except in world 7. The house which has a ghost flying around it. I can not find the 3rd coin! The second gold coin is behind the huge white ghost in the one room, then you go thru a door and there's black birds flying around, then you reach the flag. I assume the 3rd gold coin is somewhere on this screen... I've jumped everywhere hoping to find a vine, but no luck. Any suggestions??? Thanks.
