Dusky Fun Box is a consumable in Glacier's Laboratory, a mod for The Binding of Isaac.

Spawns a Jack-in-the-box.

The box has a chance to attract nearby enemies, it detonates itself at a random time.

Jack-in-the-box's explosion effect is randomized, and is sometimes extremely dangerous.

Holding the button that uses the card will instead set it up as a trap.

When the trap is triggered, it turns all non-boss enemies nearby into Boom Flies. These Boom Flies has a 10% chance to create Mama Mega! explosion and instantly deal a full heart of damage to Isaac upon death.

Cannot be set up as trap if mimicked.
