Donkey Kong 64 features a unnamed bat enemy found within certain stages such as Fungi Forest, Creepy Castle and Crystal Caves. This enemy would reappear in future games such as DK: King of Swing but under a seemingly new name: Flipflap.

It turns out that this particular name was already used for this enemy back in the Japanese localization of Donkey Kong 64. In the bestiary within the official Japanese DK64 guidebook, they are named フリップフラップ (Furippufurappu), which of course translates to Flipflap in English.
