BringBackSquilly
This plugin returns the Squilly respawn mechanic/glitch to 1.21+. This is useful if you want a newer-version prison.

The quirkier aspects of the mechanic are also preserved. If you place a slab on your respawn point, your Y coordinate when you respawn will also be offset by 0.5.

Squilly Mechanic Usage
Place a boat or shulker blocking your respawn point. You'll then respawn on top of the pillar.

Also see Squilly's original video on the mechanic.

Plugin Installation
Simply put the jar file in your plugins folder and restart your server. It will start working immediately with no setup or config needed!
