Bullshit everyone goes bananas over Wario and Waluigi and dont' give a shit about Tanooki Mario. 1 boost = 1 pat on his belly
I've just been informed by @Gveskoyeno that tanooki are known for having enormous balls, so now the boost is to pat those bad boys, sorry I don't make the rules here
@aobehr In Japanese folklore tanuki are known for their giant testicles.
