Lemmy Koopa:

Lemmy is one of the two youngest Koopa Kids, and Iggy's twin brother. He's sort of an ignoramus, and this seems to work in his favour more often than not; He's also a total idiot who takes everything way too literally. I guess he fell off that ball of his too many times. But I'll say one thing for him, he's a dedicated Koopa. Lemmy would do anything to make his daddy proud. So what it comes down to is that if you should happen to meet one of the seven Koopa Kids in a dark alley, you'd have your best bet for it to be Lemmy.

Lemmy was known as Hip in the Super Mario Bros. 3 and Super Mario World cartoon series.

  

 

  Hip Koopa:

Hip's personality is the same as Hop's.  Really, it is. So just go over and read the bio I wrote for Hop Koopa and save me the trouble of having to repeat myself.  There's some other things about Hip, though.  He's uh, got that ball.  And he balances on it, too.  He's also pretty short, shorter than Hop. But on the other hand, that doesn't exactly measure out how much evil a Koopa can do for the world, so who cares?
