Here's another Borderlands 3 Easter Egg for you, and this one is for the Destiny crowd.
Fans of Destiny will appreciate this Dinklebot Easter Egg in Borderlands 3.
If you head over to Promethea ,once at Maliwan Modulars you will need to go toward Skywell Station-27. This area looks like the Moon, and this is where the Dinklebot enemy, which looks like one of the Ghosts in Destiny, is hanging out.
Once the Dinklebot is destroyed, it drops a Legendary item called Loot-O-Gram. If you take it to Crazy Earl on Sanctuary, he will give you a reward.
Only thing is, Earl doesn't give you anything special. Just a common weapon. However, this bit is also Destiny related, as it's a poke at Legendary Engrams dropping common items instead of something cool.
Because the Dinklebot is a rare spawn, it may not be there when you arrive. If that's the case, quit to the main menu and load back into the game. This will put you back at the fast travel point, where you can run back to Station-27 and, hopefully, Dinklebot will have spawned.
