The Old hub has been re-designed on Quacktopia. It was re-designed on the 9th of March 2020. In this new hub, you are in Adventure mode, this means you can't accidentally fly off of the parkour.
There is a merry-go-round where you can ride on llamas, chickens and loads more animals! There is also, hide and seek, a small town, beach and a few sneaky little extras. The second half of the hub is closed off and will be used for events. On the beach area there is a diving board for you to dive off of into the sea.
The Back Half to the Hub
If you walk forward when you spawn in (/spawn) and turn right you will come to an area in which there is a stage, relaxation room and Catwalk.
