Hidden Jerry

Hidden Jerry is a mob that has a chance of appearing when a player earns Skill XP.

Rarity
There are 4 types of hidden Jerrys: Hidden Jerrys can only take per hit. can also be used to damage them. All have the possibility to be runic. When killed, they drop a Jerry Box that corresponds to the color (for example, Golden Jerry drops the Gold Jerry Box). If another player kills the summoning player's Hidden Jerry, the summoner has pickup priority of 25 seconds, after which anyone can pick up the box.

Drop Message
Possible chat messages (with, , , or and their colors):

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 which cannot be reset by changing islands.

Trivia

 * Similar to the and Spooky Mobs, Jerries will run from the player that spawned them when spawned. This often causes the player's Hidden Jerry to fall into the void, into lava, or run a large distance from the player. If the player's Jerry dies due to fall damage, they will still drop a Jerry Box as long as the player had hit it at least once.
 * Like Spooky Mobs, the and  enchantments do not bypass their defense.
 * Using the potion effect will instantly kill a Hidden Jerry.
 * Fishing Rods could at some point bypass their.
 * Auto-pickup does not work on them.
