Withered Deku Baba
Ocarina of Time
Withered Deku Babas are the first enemy Link encounters in the game. They are unable to damage him unless he purposely walks into them. They are notably weak enemies, requiring only a single sword slash that results in an instant death. When defeated, they typically drop a Deku Stick. They can be found in Kokiri Forest and Inside the Deku Tree.
Isn't that a Deku Baba?
Withered Deku Babas in Majora's Mask appear in an identical fashion as they did within Ocarina of Time. They can be found in Termina Field, Southern Swamp, and Woodfall Temple. Again, they can be easily defeated with virtually any weapon.
