Inhaling the gas they belch will make you sleep for a week. They prefer unsanitary places.
The combination of garbage bags and industrial waste caused the chemical reaction that created this Pokémon.
Wanting more garbage, they follow people who litter. They always belch poison gas.
Unsanitary places are what they like best. They can be spotted in Alola, often with Grimer in hot pursuit.
It gorges on trash until its stomach is full. Then it belches toxic gas. An unlucky whiff of gas will put a person in the hospital.
