Hey, I'm new here. Anyway, for some reason King K Rool can drop through platforms while he's using the blunderbuss, so long as he hasn't sucked anyone up yet. He can even slide left and right a little as he's falling. In my limited testing I've almost managed to launch people into the projectile by dropping down. I can easily see this used as a bait tactic, and if done right, it'd be hard to punish. It's also pretty silly on platform based stages.
I haven't noticed any other characters that can do that yet.
