Sergeant Smoggolor or General Greenthumb is a character in Park Patrol.
Sergeant Smoggolor had his beginnings as a toy based on General Greenthumb. He had a bad owner though, and was thrown out once. At this time, Miasma comes and transforms him. He then turns the helpers into dust, and Chibi-Robo helps them. The flowers change him back temporarily, but Miasma reverts the changes. However, Chibi-Robo changes him back, and he tickles Miasma during the fight. He, however, dies from this.
