Hoppin' Jack

The Hoppin' Jack is a Hardmode pumpkin-like enemy that will only appear at night during the Halloween seasonal event or until 4:30 AM the day following reaching the 15th wave of the Pumpkin Moon Event before 4:30 AM. It will display the message “The spirit of Halloween penetrates the air...” at dawn (4:30 AM). For the rest of the day, all special effects of the Halloween season seasonal event will occur including Hoppin' Jack spawns. At 4:30 AM of the next day, the message “The spirit of Halloween rests” will appear and all Halloween events will no longer occur until the Halloween season begins again or the player completes the pumpkin moon again.

It attacks by hopping towards the player in a manner identical to most Slimes. The difference, however, is that the lower on health it is, the quicker it becomes.

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 or Slimer/King of Slimes  achievements.

Trivia
