Donkey Kong (level)

Donkey Kong is the stage where Mario faces Donkey Kong as the final boss for the first time in Mario vs. Donkey Kong. After running off with three Toads, Donkey Kong imprisoned them and threw spiked Barrels from above.

Layout
Donkey Kong's battle is split into two phases.

During the first phase, Donkey Kong will throw occasional spiked Barrels and flip a switch to change which key is available. Mario must grab each key when it appears to free a Toad of that color.

Once all three of the Toads are freed, the battle moves on tho the second phase. Donkey Kong will throw more spiked Barrels and eventually a larger Barrel. Once the larger Barrel moves off the screen, the Toads will return with it and place it down. Mario must then grab it and hit Donkey Kong with it. Donkey Kong will repeat his process, throwing more and more spiked barrels each time he is hit, which in turn makes it harder for Mario to avoid them. Once Donkey Kong is hit four times, he is defeated.
