Morton Koopa, Jr.:

Morton is a hot-tempered, loud-mouthed jerk. His personality runs along a similar line as Roy's, though he's not generalised as being as extreme in that sense. He's short and stocky in stature, and also quite strong. So don't act up towards him, or he'll kick you in the face or something. Bowser's real proud of him, so all us underling-types get to enjoy tossing lavenders at ol' Morty's feet whenever he's around. Bleh.

Morton was known as Big Mouth in the Super Mario Bros. 3 and Super Mario World cartoon series.

 

 

 

Big Mouth Koopa:

Big Mouth lives to annoy people. Given a subject, he'll just keep spewing this endless monologue forever, until you find a way to keep him quiet (two-by-four helps). I'm sure he can get through masking tape pretty quickly by now.  But the worst thing you can do is ask him his opinion on a matter. Sure, he might consider himself the single greatest orator of our time, but the way the rest of us see it, he's bloody full of hot air. And he's hot-tempered too. Which can be trouble, if he's around, say, Kootie Pie. That amount of screaming and ranting really starts to carry its weight after a few hours. Ultimately, I'd think I'd prefer being stranded on a deserted island for the rest of my life with Oogtar than with Big Mouth.
