Trubbish resemble a full, green garbage bag, knotted on top. They have oval-shaped eyes and a toothy mouth, and arms that look like trash spilling out of small tears in the bag with pink and blue colored objects protruding out of them. Their feet are green and stubby.
Trubbish emit burp-like gases which, when inhaled, will render the victim bedridden for a week.
This Pokémon was created when a garbage dump accidentally had a chemical change of some sort.
