DIRT: A type of powder element, this element lets the radioactive elements pass trough and grow plants on it.
SEED: A type of powder element, another way to make plants. A SEED on DIRT will react with WATR and the seed will turn into VINE
MUD: A type of liquid element, created when WATR touches DIRT. You can dry it with air pressure or elements with high temperatures (LAVA, FIRE, or HEAT)
DDRT: A type of solid element, Dry DIRT, non-flammable and you can turn it into DIRT with air pressure.
