Plantera
so this is an idea i got from reading the thread made by zimmerzimmer on his staff of regrowth changes. so thanks for that. this would work like a placeable cleminator. you would place it on the ground in your area of choice and then place one of the cleminator fluids in it. then for a certain distance (25 blocks eitherway?) if the blocks were compatable the biome would change to the fluid's biome. this is just a basic idea/framework so feel free to give me any changes/improvements. sorry for any bad spelling or if i posted this in the wrong place.
