Extravaganza!

Ball Pools are set up with a Ball Pool Registration Table, and the pool blocks define zoned areas that players can throw Festive Balls into. The zones are adjusted with the Wrench Aganza, a wrench that switches between several settings. Festive Balls are not crafted directly; players first collect Common, Uncommon and Golden Coins, which can be found by exploring some mineshafts, and then craft a Ball Distributor. A Ball Distributor is crafted and then used by right-clicking it while holding coins; the rarity of the coin inserted sets whether one, two or four Festive Balls are launched.

The Merry-Go-Round is a large attraction whose speed can be made slower or faster, and the Wrench Aganza selects one of ten different powers for it. Helium Balloons rise after they are placed and burst about ten seconds later. Food includes Candy Canes, Hot Dogs and Popcorn, and the Popcorn Machine must be crafted first, along with Empty Popcorn items.

Extravaganza! requires Fabric API and MModding Library on both Fabric and Quilt. Servers that run it need every player to install it too. It is published for 1.21 – 26.3 under a custom license that is not open source, with public links for source code and the issue tracker.
