Hidden Jerry

Hidden Jerry is a mob that has a chance of appearing when a Minion mines a block, or when a Player earns Skill Exp.

There are 4 types of hidden Jerrys; Green, Blue , Purple , and Gold , each having 3, 4, 5, 6 respectively, but can only take 1 damage per hit, though burning effects can surpass the defense. When killed, they drop a Jerry Box that corresponds to the color (Golden Jerry drops the Gold [] Jerry Box)

When a Hidden Jerry is found a message will appear in your chat letting you know that a Jerry has spawned! There will be a floating head that will fly around for about 3 seconds before spawning a Hidden Jerry. Once spawned, the Jerry will quickly run away, sometimes falling into the void or off a high area causing you to lose the box. Using a bow from a distance can however be used to shoot the Jerry without it running away. The Jerry spawns randomly but has a cooldown of about 6 minutes.  For more details, see the Jerry Box wiki page.
