Halloween Chest

Summary
This can only be found in the Lord Pumpkin Jr. boss on the Halloween Event 2017. This would only spawn if you defeated Lord Pumpkin Jr.

Background Story
After defeating Lord Pumpkin Jr., the survivors opened his coveted treasure chest to find a box containing instructions for painting with a "spooky color scheme". As it turns out, instead of pie-making, the pumpkin had turned to art to distract him from his all-consuming internal anger.

However, if you looked elsewhere, another group of survivors strangely similar to the last opened the chest not to find instructions but to a seemingly magical torch.

Trivia

 * Second boss exclusive event.
