This is a monkey wrench in the Weapons shop.
Monkey Wrench is a Weapon found in the Weapons shop dealing an initial damage of 46.8 at slightly slower than normal speed, bringing the overall damage to 36 points. This weapon is stronger than a Mail Box and the Weed Wacker but is weaker than the Powerdrill. The weapon costs 15 Brains pieces but can only be sold for half the price. Although it is available at an earlier level than other weapons at the next slot, it is not well worth the price.
