In this datapack, Any mob (With a few exceptions) has a rare chance of being randomly resized.
This requires the recent 23w51b snapshot to work!

Features!:

-Sizes are chosen based on Four types; Mini (0.5x to 0.75x), Lesser (1.25x to 1.75x), Average (2x to 2.75x), and Titanic (3x to 4x).
-Health, damage and explosion radius (For creepers) also scaled with size.
-Baby mobs cannot be randomly assigned a size, instead, animals can be bred to have similar sizes to their parents, randomly adding or subtracting size with each generation. (This only works with mobs born from Megafauna)
-Hostile megafauna can only spawn on the surface at night, and cannot spawn from spawners.
-A few mobs are excluded from becoming megafauna, including the following;
Villagers, Iron Golems, Snow Golems, Vindicators, Evokers, Vexes, Pillagers, Ravagers, Piglins, Piglin Brutes, Zombified Piglins, Slimes, Magma Cubes, Sniffers Wandering Traders, Wardens, Withers, and The Ender Dragon
