Created for Modfest Toybox, this joke mod adds some radioactive materials, and implements a radiation mechanic kind of.
Features
Radioactive Fun Goop: This stuff is absolutely NOT a toy and should be avoided at all costs
Waste Block: A Barrel of nuclear waste filled with weird goop. Makes weird sounds with noteblocks.
Radiation Mechanic: When near radioactive blocks or irradiated entities, you will randomly take small hits of damage, the chances increase with the amount of sources.
Radiation Sickness: When irradiated by enough sources, you are effected by radiation sickness. This means you are now a radiation source!
