Addon: Bolt & Buddies
The Bolt & Buddies mod will bring Mammoths and an unusual mob called the Brummer to Minecraft.
Created by Lordbigbrain


A new peaceful mob, the Brammer, has been added! It has 45 HP. When the Brammer grows up, it drops its horn, which can be used to craft a new exciting weapon - the BIG crossbow.
The new crossbow is crafted using Brammer horns, which you'll find during your thrilling adventures. This invention will be an indispensable companion in protecting your valuables from hordes of monsters, as it can shoot at three enemies simultaneously, dealing balanced damage to all of them.
