This is a particularly hilarious one, as it seems the Diablo event Treasure Goblins don’t just jump out of portals, they also send players into them! While players have been farming them constantly, the goblins have had enough and are now using next-level tactics to get rid of as many players as possible.
This particular one, caught by MemeStarKeem (or rather, the goblin caught them), used the players’ desire for the mount/cosmetics and lured them right on top of one of the capital city portals!
This is exactly the kind of stuff that creates memories that will stay with you for years and years, and is one of the reasons events like these are just great.
