Roger the Potted Ghost

Roger the Potted Ghost is a boss character from Super Mario World 2: Yoshi's Island and is located in the final castle of World 2. Roger started out as a lifeless flower pot, but was transformed by Kamekâ€™s magic into a large ghost named Roger. He's amorphous, but his face resembles Dangling and Caged Ghosts.

To defeat him, the Blue Yoshi had to push Roger and his pot over the edge of the platform. This was a difficult process, as two green Shy Guys were pushing Roger in the opposite direction. Throughout the battle, Roger will lunge at the Blue Yoshi, knocking him or her away. He also shot blue flames which home in, forcing the blue dinosaur to stop pushing and get out of the way. If the Shy Guys are pushed off the edge, Roger will be helpless and won't be able to move.

He may or may not be the inspiration of Jarvis, a ghost similar to him in Luigi's Mansion.
