Do Not Open: Princess Bubblegum’s event quest
- Finish Buddy Up first. Without it, Princess Bubblegum only says: “If you find anything unusual, bring it to me. Preferably in a container. Preferably not your mouth.”
- Go to the Candy Kingdom gate in the hub and press E on Princess Bubblegum (she is wearing her lab coat).
- Accept the job. “Three research boxes fell off a cart near the old campsite in Mount Cragdor. Bring them back sealed. If anything inside moves, that counts as a problem.” Answer “I’ll bring them back.”
- Find all 3 boxes in Mount Cragdor. The tracker reads “Recover all 3 research boxes at the old campsite (Mount Cragdor) 0/3”.
We reached section 3 of Mount Cragdor without seeing a pickup prompt, so the campsite is probably further in. We will add box locations with screenshots as soon as we find them.

FAQ
Why doesn’t Princess Bubblegum give me a quest?
Her Do Not Open quest unlocks only after you complete Buddy Up by talking to Finn in the hub. Before that she just says to bring her anything unusual.
How do you get the Lab Coat Princess Bubblegum skin?
It is the reward for the limited-time Princess Bubblegum quests from Update 2, which started on October 21 with new quests every 2 days. Do Not Open is the first one: recover 3 research boxes from the old campsite in Mount Cragdor.
How do daily quests work?
Three quests on the notice board in the hub, each with a Start button. Finishing all three adds a 25-Gem bonus. They reset daily; the board shows a countdown.
Is Do Not Open time-limited?
Princess Bubblegum calls it “a small, time-sensitive job”, and Update 2 quests are limited-time, but the quest tracker shows no countdown.
