This datapack allows you to give Happy Ghasts a much needed speed boost by "feeding" them snowballs
Download the latest release and save it to your world's "datapacks" folder.
Once installed, grab a few stacks of snowballs, and hop on a Happy Ghast. Every five seconds, the datapack will check if you're holding a snowball. If you are, then one snowball will be deducted from your hand and "fed" to the happy ghast, applying a speed bost for the next five seconds.
For reference, flying level,
Compare this to elytra speeds, where a rocket accelerates the player to ~35 m/s in level flight and where horizontal speeds in excess of 45 m/s are possible during a dive
To uninstall the datapack, simply remove it from your world.
To be extra safe, you can also run the command:
/function gitb:reset
from the ground / without any snowballs in your hand to make extra special sure you've reset the Happy Bois' speed attributes.
