He's a little sloppy like Luigi in my opinion. Yoshi has a very good "beat-up" move, and can actually KO. However, Yoshi does not have a triple jump. Even though that second flutter jump sounds nice, it's still not that great...It's little too inaccurate. Love how Yoshi is the master at Home Run (In actuality, the Gan Man is only if you can execute the you-know-what-I-mean-right?).
All right, here's a good record to beat. And another, for my generosity.
Mario Bros. Madness (Vs. Mario + Luigi, Super Mario Bros. Stage, Timed Match): 14 KOs
Seconds, Anyone? (Infamous Captain Falcon fighting): 0:1:11
