i had this idea that creepers vary based on biome

cat creepers are fast and silent, but have a weaker explosion. they tend to appear near villages and jungles
dog creepers travel in packs through forests
bear creepers are big, loud, and slow, but their explosion is twice the radius of other creepers. they live in tundras and taigas

i also thought about doing horse creepers for plains/savannahs & goat creepers with horns for extreme hills/mountains, but i didnt get to drawing them yet
