When used, Diddy Kong leaps forward towards the enemy, latches onto their face, and remains there until the player presses the attack or special button to deliver a single smack attack via a headbutt (not unlike a pummel). The distance traveled can be changed depending on whether the Control Stick and special move button are pressed simultaneously or not. As the move sends him forward, it can be used as a recovery, and it can be used in conjunction with Rocketbarrel Boost, as it does not put Diddy into a helpless state afterwards. If the player presses an attack button during sideways momentum, Diddy Kong sticks a foot out, and will kick the opponent instead of latching on. However, this kick prevents him from using Rocketbarrel Boost and if Monkey Flip's kick is used far off the stage's edges, it is possible for Diddy Kong to become helpless with little chance of recovering back onto the stage, accidentally KO'ing himself. By pressing the jump button after latching onto an enemy, it is possible to jump onto the enemy's head and push them downwards, which performs a Footstool Jump. The Monkey Flip can also set up a Diddycide, although the Footstool Jump is almost always a better option. Like Chomp, this attack can block some characters' recovery in Brawl.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
While Diddy Kong has never used this move in any Donkey Kong game, Donkey Kong uses a similar move in Donkey Kong Jungle Beat, where it was used to grab and pummel enemies. However, it seems to have inspired Diddy Kong's forward/backward Trick Shot in Mario Tennis Aces, which greatly resembles Monkey Flip and functions similarly.
