Boobawamba

Boobawamba is a room or corridor but the lights are out. There are five objects that have a 50/50 chance to be there. Note the ones that aren't there, and at the end will be five buttons labeled numbers 1 through 5. Push the ones dedicated to the respected object. Lets say objects 1 and 4 weren't there. Press buttons 1 and 4. This will unlock the door to exit the room/corridor.
Person 1: "Did you see that fortnite added a hidden boobawamba to the reload map?"
Person 2: "Yes, and I heard that if you exit it, you get an op mythic or something."
Person 3: I got it once and it does 200 damage instantly.
