Infinite Snowballs!

Infinite Snowballs lets players throw unlimited snowballs in Survival mode without constantly crafting or collecting more. As long as you are holding at least two snowballs, every throw is replenished automatically. If you have fewer than two snowballs, the effect is disabled and the mod behaves like vanilla Minecraft. It's best used in survival mode- as in creative mode it will keep giving you snowballs as you DONT use them up.
