Limbs of pool noodles? Ever hit someone with a Forward Air or Forward Smash? Diddy plays intensively satisfying for me because of those moves. He can even KO with Up Tilt. Up Smash and Forward Smash also being very reliable kill moves. You can build up damage very easily, especially compared to Sheik and Pikachu, who need far more hits to do the same amount of damage Diddy can do. You can also spike people very nasty with Down Air, chain up to 4 Back Airs from a grab, do good damage and knockback with the Monkey Flip Kick, and of course the Banana shenanigans which deepen Diddy's playstyle. He's just overall a very fun and satisfying character to me, but it does take quite a bit to get real good with him. Which is worth the investment if you ask me.
