Editing Stage 4-12

'''Stage 4-12''' is the twelfth and final level in the [[Jungle (Donkey Kong)|Jungle]] in the [[Game Boy]] version of ''[[Donkey Kong (Game Boy)|Donkey Kong]]''. The level is a boss battle against [[Donkey Kong]].

[[Mario]] starts on the middle platform with two platforms on each side for him to [[jump]] on. There are four [[vine]]s on each side for him to climb up to get to platforms on each side. Donkey Kong is on a wide middle platform with [[Pauline]] on a platform above him.  

Like the other battles, Donkey Kong rolls and throws [[barrel]]s down to try and hit Mario, the difference being there are holes in the ground into which rolling or thrown barrels can disappear, therefore Mario cannot grab a barrel unless they are thrown and land on the platforms on the sides. Mario can [[Handstand]] to deflect the barrels off his feet to get a barrel; however, even if he does this, he will not be able to reach Donkey Kong as he cannot climb [[Vine]]s while carrying a barrel. Mario must be on the side platforms to be able to grab a barrel and throw it at Donkey Kong to hurt him, but this time, [[Poison Mushroom]]s fall out of broken barrels, so Mario must stay clear of them to avoid being shrunk. Donkey Kong takes three hits to be defeated as in previous battles; once hit three times, Donkey Kong will be defeated and the level will end, but Donkey Kong gets up again and grabs Pauline before he runs away.

Donkey Kong and Donkey Kong Jr. continue running until they reach [[Brick Block|brick]]s. Donkey Kong is on the other side of the bricks while Donkey Kong Jr. is on top. Mario then grabs a [[Super Hammer]] to break the bricks as the surprised Kongs flee, with Mario continuing to give chase, leading him to the [[Desert]]. The player is then given lives based on their score.
