upon making a superflat custom world with the following preset:
minecraft:bedrock,16*diregoo:gooblock,diregoo:gooblockterrain;minecraft:plains
turning structures off
turning difficulty to peaceful

you will have a superflat world consisting with a crust of terrain goo and then 16 blocks below that of the purple goo

grab a goonade and just spam them EVERYWHERE (like throw them as fast as you can as close to you as you can, hitting as any blocks as you can)

open F3 and note the incredible amount of entities ("E:[being rendered/not being rendered]" and particles ("P:[particles currently being rendered]) being created

Diregoo version: 1.1.0
