Mario has again locked up Donkey Kong, this time in a cage. Junior is off to help his papa. To do this he has to evade snapjaws and attacking birds. He can knock down a bird or snapjaw by dropping a fruit on them. Now to the difficult part. Once you reach the edge next to the cage, you have to time your jump perfectly to grab the swinging key and unlock part of the cage. After 4 sections are unlocked Donkey Kong is freed.
