Princess Bubblegum uses it only once, against the army of evil hands that attack her and Lady Rainicorn, before the hands snatch it away.
The Ball Blam Burglerber is a black gun with a glass window and a decorative lightning bolt on its side. It appears to hold six balls through a glass hopper that comes out of the back and to be pump-action, and looks very similar to a children's ball launching toy. However, in the storyboard for "Lady & Peebles," it looked more like a revolver and was named the "Ball Buster." The weapon is similar to a grenade launcher due to its explosive function.
