About
This resource adds to your server ability to extend default managment by customizable balloons. You can create your unique network using included functions that aren't available in the basic minecraft package. This plugin also doesn't use any resource packs so you don't have to force players to download additional data. The only limit of this resource is your imagination.
Thank You!
