This is a Bedrock realm called Mob Heist and it is totally brainrot in a good way.
It feels like the whole point is just to jump in and mess around and try to steal stuff and cause chaos with mobs. It is not super serious and it just feels like the most fun you can have on Bedrock.
If you want a place that is silly and fast and you just want to join and play without thinking too hard this realm is perfect.
