Your mom when she blows him.
I'm not sure, I heard that he likes Daisy, but I've never seen him do so.
In some games, it's shown that Waluigi likes Eggplants. And in Mario Party 3, it's hinted that Waluigi likes Piranha Plants and likes using Poison Mushrooms on opponents.
Oh yeah! It does say "Who" isn't it. Well, from watching the character celebrations in Mario Power Tennis, I say he likes Peach because he and Wario were pretty jealous when Peach blew a kiss to Mario and Luigi.
It said that Waluigi actually likes Daisy, not Peach. MPT was an old game so I think that Waluigi actuallu has an interest for Daisy. That is probably why he hates Luigi. --KamariU (talk) 23:04, July 1, 2014 (UTC)
