Goopygon

Goopygons spawn in the swamp biome, and they look like slimes, but are nutural. Spawning only in water, and can be mounted if given slimeballs. With 10 hp, half of your health, and do 2 dmp when aggravated. Drops, cod and slimeballs. If goopygons touch the ground they melt into the ground. If spawned in the nether, will turn to obsidian. If spawned in End will explode since these mobs are shy.
