The Slingshot

The Slingshot is a weapon used in Battle Bears: Zombies. It is a jackolope with a rubber band attached to its horns. The ammunition for the slingshot is jackalope waste, which are black jellybeans. The slingshot inflates and causes Huggables to explode. Huggables caught in the resulting explosion can also perish. The slingshot is also used to kill the Bearzerker. The black jellybeans suck away at the rainbow energy which power the Huggables. By shooting the Bearzerker over and over, you eventually drain it of its life force, and choke it to death. 

It is planned to be added to Battle Bears Zero as a weapon as revealed on the Battle Bears blog, but nothing more is known about it.
