Bowser

Bowser is the real primary antagonist in Mario Plush Forever. He first appears in Episode 2 where he asks Dr. Koopa how to get the cure from Yoshi. Dr. Koopa suggests that they cut off his limbs and use his head as a football. Bowser says that Dr. Koopa must do whatever he can to get rid of the farts. Bowser then farts in Dr. Koopa's face. He then appears in Episode 6 where Mario and Luigi fight Bowser so the bros can get Yoshi back. In the end Luigi throws a ghost mushroom at Bowser making him vomit. Mario then farts on him setting him on fire. Bowser almost falls into the lava, until he farts uncontrollably. He the runs (or farts) away. In the end of the episode, Dr. Koopa then goes to Bowser with a tray of tea. Dr. Koopa then sees the most horrific thing ever. The ghost mushroom transformed Bowser into Giga Bowser. In episode 11 we see Giga Bowser charging at the castle. The gang then runs to their carts and drive away. As our heroes drive, Giga Bowser is following right behind them until Donkey Kong gives him the slip, literally. After the bros gather up an army to defeat him, Giga Bowser decides to fight fire with fire by gathering up his army. In episode 12 after a long and bloody war Giga Bowser kills almost all of the heroes team mates, and when all seems lost, all of a sudden Master and Crazy hand appear and beat the crap out of Giga Bowser sending flying into Sonic's world presumably killing him. However in season 2 episode 1, Dr. Koopa mentioned Bowser's name signaling that Bowser is alive.
