I was playing infection (desert) and I got a Rolf so I kept Rolfing till I got all of the items you get from Rolfing. Then I thought what if we added enderpearls to the Rolf's!
I thought the uses of enderpearls could be like snowballs, but instead of bliding/exploding damage with 0.5 hearts, use it for grenades that do 5.5 heart damage.
