Bowser

Bowser is a villain in Super Mario Plush. He usually captures the princess because of how beautiful and hot she is, revealed in Robot Revolution. Even though he does capture the princess, his plans usually get busted by Mario, Luigi, Sonic, or even kids. He does have minions to help him though.

Amiibo Bowser (Mario Goes to another dimension-Jr's New Pet!)
Bowser was an Amiibo from Season 1 to Mid Season 4. At this time, he was only an Amiibo, which made him smaller than a lot of the other plush characters, and maybe weaker.

Fat Bowser (Bowers's Ego-Bowers's Ego)
Fat Bowser was Bowser when he lost his Mojo. Bowser Jr tried to point it out to Bowser, but he didn't see at first. Kamek helped him turn into...

Puppet Bowser (Bowser's Ego-Stop Capturing the Princess!!)
Puppet Bowser was the closest to being a plush. He was bigger, but didn't have any legs. Now, he was stronger, too. Kamek then used a spell to turn him back, but it turned him into...

Plush Bowser (Stop Capturing the Princess!!- )
Bowser is finally a plush. This is the Bowser that is used from now on.
