My NOTP for them: Bowser. Not quite as intense, but still, blegh.
My OTF (One True Friendship) for them: TEC and Twink. Oh yeah, and Perry!
My OTP for them: Mario
My second choice pairing for them: Geno
My fluffy pairing for them: Mario
My angsty pairing for them: One-sided TEC/Peach, I suppose. :P
My favorite poly ship for them: Bowser & Mario
My weirdest pairing for them: Faris from Final Fantasy V. Tomodachi Life inspires a lot of crack.
