Here's something interesting: Smash 3DS got rated E10+ on the Nintendo.com page. Beyond the question of "How did it get E10+ when Melee and Brawl got Ts?", there is no tag for "crude humor". Provided that it's not just a preliminary rating off of only revealed info, maybe Wario's moveset is ditching the Wario Waft?

Hmm, it would be interesting if the Waft instead buffed him with "grossness" and basically acted as a EX charged/taunt-buff that gives extra knockback on his specials to interpret that as the opponents wanting to get away from him.
Do you smell what the TechPowah's cookin'? It smells delicious.
We've been insane since the dawn of sentience. Should be okay.
