Kiki

"Monkey business! Done! Bye bye! Oooh! Kiki!"

- Kiki (Link's Awakening)

Kiki is the name of a recurring monkey character in The Legend of Zelda series.

A Link to the Past
Kiki is a little monkey who first appears in A Link to the Past. He shows up when Link is wandering through the maze of brush on his way to the Palace of Darkness, the first Dark World dungeon. Kiki loves rupees more than anything in the world and asks the young hero for 10 Rupees, after which he will follow Link. If Link is hurt while Kiki is following, the monkey will run back to the maze, and Link will need to give him another 10 Rupees. When both Link and Kiki reach the palace entrance, Kiki tells Link he can open the door in exchange for 100 Rupees. If Link pays him, Kiki looks around for a bit, then jumps on the roof and hits a switch, opening the door. If Link declines to pay either time or is hit by an enemy, Kiki will run off, and Link must return to the maze to find him.

Link's Awakening
‎Kiki also makes another appearance in Link's Awakening. He is found southeast of Kanalet Castle and is hungry. When he receives the bananas during the Link's Awakening Trading Sequence, he and several other monkeys build a bridge to access Kanalet Castle. Also, they leave behind a stick, the next item in the trading sequence.

If Link approaches Kiki while with Bow-Wow, Kiki and Bow-Wow instigate a fight. After a while, Kiki runs away by jumping across the river.
