Trubbish

Trubbish, known as Yabukuron in Japanese, is a Poison-type Pokémon introduced in Generation V. It first appeared in Pokémon Black and White. Trubbish resembles a dark green garbage bag with a knot at the top that acts as ears, and has pink and blue objects protruding from its sides, giving the impression of trash spilling out. It is formed from a chemical reaction of mixed domestic and industrial waste. Trubbish emits noxious, burp-like gases which can cause anyone who inhales them to be bedridden for a week, and are potentially fatal to young Pokémon and children. It prefers unsanitary places like garbage dumps, where it feeds on trash and rotten food. When it befriends a person, it ceases emitting foul odors. In the games, Trubbish evolves into Garbodor starting at level 36.
