The Hoppin' Jack is a Hardmode pumpkin-like enemy that will only appear during night during the Halloween seasonal event. It attacks by hopping towards the player in a manner identical to most Slimes.
Notably, despite using the Slime AI, it is not treated as a slime for most other purposes. Hoppin' Jack drops no Gel on death, will remain hostile to a player with Royal Gel equipped, and killing one is not necessary to earn the Gelatin World Tour (on the Desktop version) or Slimer (on Console and Mobile Versions) Achievements.
