The Monkey Spear was a brown, wooden staff with a head of a monkey at the top of it. The monkey was white and brown, with brownish yellow ears and red eyes. It had also a tail on the back.
When using the Monkey Spear, the user would gain the appearance, strength, agility and balance of a monkey. If it was used too long or if the wielder called out its name then the user would turn into a complete monkey, and if left unchecked, the user would start thinking like a real monkey - his or her human memories would be erased until the staff was taken away. It would additionally launch monkey spirits. When combined with the Rooster Booster, It turn the user into a gorilla rather than a monkey.
