Donkey Kong Jr. (microgame)
From the Super Mario Wiki
Donkey Kong Jr. is one of 9-Volt's microgames in WarioWare: Twisted!. It is set in the game of the same name, specifically Stage 4. It reappears in WarioWare Gold in 18-Volt's set, where it takes place in the first two stages, with the third difficulty level taking place in Stage 4.
The objective is to have Donkey Kong Jr. climb up the chains and insert the two keys into their locks, freeing his father from Mario. In WarioWare Gold, Junior must climb the vines to knock the fruit down in the first two levels.
