A Jump is a hostile mob that spawns in the Overworld. They look like brown boxes with long black legs. They can jump really high to give critical hits to the Player. Making a high jump will take away half-a-heart from them, but when they die from fall damage (if they don't kill you first) thay won't drop any items. Instead of running, they hop toward you. When a jump does a high hump, it may fall on another mob inflicting damage on it.
Drops: Jump Leg (0-1) (used for making High Jump Potion)
Part of the Overworld Life Mod.
