Mad Scrub

Mad Scrubs are enemies from Ocarina of Time and Majora's Mask.

Ocarina of Time
The Mad Scrub is a variation of the common Deku Scrub enemy from Ocarina of Time, and bears foliage resembling the leaf colors associated with autumn. They are found in the Sacred Forest Meadow when Link is a child and in the Kokiri Forest when Link is an adult. Unlike the Deku Scrub, the Mad Scrub will not attempt to return to its nest after being injured, and will simply shoot more Deku Nuts at Link until it is killed.

Majora's Mask
Mad Scrubs inhabit the Deku Flowers in the Deku Palace and Woodfall and primarily serve as obstacles that allow their flower to be used after they are defeated. Unlike in Ocarina of Time, these are the only type of Deku Scrub fought as a normal enemy; normal Deku Scrubs are not enemies in the game and Business Scrubs will not attack Link before offering him their wares.
