Kirby has no Glide toss
But he Can stop the Peanut-Popgun with the 3rd animation of his jab (the blue punches). Its not a rock solid deffense, but since it has multiple hits, it can stop some incoming peanuts.
The only way to get hit is if you take a peanut near a part above his eyes on the top of the head. That or if your opponent is an extremely good timed player and manages to make a peaunut go through the jab.
I found this messing arround trying to find something useful to use against DDkong. If some one could mess arround with it and make something out of it, even better.
It won't win you the match but it can make DD reposition himself, or make him doubt the popgun aproach in general and not use it in the match.
Other than that, Stayz away from da Bannanaz
. Fight him in the air and watch his Fairs.
