^ Neutral B!
And I've been doing that a bit (thoug Diddy Kong is like one of the 24 characters I use; ya!
). using Bananas is a epic mindgame, especially followed by his forward B (in air; it's his flip thing, right; I forget when not in battle sometimes!
), forward air, or sometimes even nAir or uAir (if they're above you). It can have some epic mind game-like combos online. I straight up comboed some Ivysaur online on Green Hill Zone from like 0 to 50% by mind gaming them with 3 to 5 banana peels, they trip, I up tilt, I do the grab move with the forward B (perfect distance), forward air, and into more banana peels. Those banana peels can have some crazy effects.
Ya, so knowing to use them is the first step. Start applying them, and it'll help you a lot. Your opponent will be more cautious, but it can throw them off like no other, since Diddy Kong is a living, breathing, moving taunt. Throw banana peels, trick them into it, be smart enough (and work on it) to avoid getting hit by them (unless you got some insane stratgey), and you got possibly one of the craziest mind games in the game (so far) down. Trust me, apply and watch your opponents die. (rhymeage!
