- Yoshi is Wabirdo
- Birdo is Wayoshi
this of course assumes a yoshi/birdo duality which is a hill i can be argued down from, BUT:
yoshi is friend to the mario brothers, while birdo shoots eggs at them in battle. birdo by this logic is the WA in the pairing,
birdo shoots eggs out of her mouth, the blessed egg-hole, whereas yoshi shoots eggs out of his butt, the cursed egg-hole. birdo takes nothing and only gives precious egg, but yoshi consumes all as an avatar for greed, just as wario does.
who, wa, where, when, how
