Helper Monkey

The Party Monkeys are a species found in the game Donkey Kong Jungle Beat. They are a helpful group, telling Donkey Kong what to do, and tallying up his Bananas at the end of every kingdom. They are often shown to be playing instruments. It is unknown whether they are related to the malevolent Minkeys or Ninjapes, which they resemble. They seem to own the small stretch of jungle known as Opening Ceremony as they are predominantly found there. Party Monkey mainly help Donkey Kong by getting him to hard to reach places. Often, a green bush that is floating in the air will have a Party Monkey in it. When Donkey Kong stands close to this bush and claps, the Party Monkey inside it will grab him and throw him up to a higher area. More rarely, Party Monkeys will hold on to each other and form a rope, which Donkey Kong can swing across on.
