Jack-O-Jelly — In-Depth Analysis
Now this tastes spooky! is the Jack-O-Jelly's in-game line, and the effect behind it is simple: it gives a pet 100 XP. Legendary, limited and out of circulation today, it belonged to the Halloween Event's second chapter (October 18, 2025).
The only source named is the Halloween Gear Box, where it shows up with a 23.81% chance, close to one box in four. It has no Sheckle or Robux price of its own; you got it by opening boxes. The reward is a flat amount of XP, not a share of whatever level the pet is at.
The wiki says it works much like Maple Syrup, another pet-XP gear. In appearance, it is a glowing pumpkin-shaped container with a menacing carved face and a light gray straw, giving off a bright, warm light.
