Donkey Kong Jr. (Game & Watch)

Donkey Kong Jr. (Game & Watch) was Donkey Kong Jr. saving his locked father from Mario.

History
Inside the forest, Donkey Kong has been held prisoner by four locks placed by Mario. Donkey Kong's son, Donkey Kong Jr., has to open the four locks and free his papa. All throughout the rescue attempt, Donkey Kong Jr. is attacked by fierce birds.

After opening all four locks, Donkey Kong is freed from Mario's grasp.

Timeline

 * Likely takes place before Donkey Kong Jr. (Arcade), as Mario is taking a much more laid back approach to capturing Donkey Kong here, sitting down and chaining him in the forest rather than putting him in a cage.
 * Donkey Kong Jr. has his umbrella here, which he also uses in Donkey Kong Jr. (Arcade).
