When Wally finally calmed down from the fit he blew upon seeing his rent bill, you both walked out to explore the rest of the neighborhood.

A stroll along the sidewalk, has butterflies surrounding you, which you were afraid of at first because of you hearing about then sucking blood, so you dodged them. Meanwhile, they were hanging on Wally just fine no problems, and he also seemed to see your fear. "Now now don't you fret. They're only butterflies, they don't do no harm." He said.

You told him about what butterflies do in your world. "Ohh... I see." He listens and just stares, not saying a word for a couple seconds. "Well frankly, I don't know what you're talking about, they don't do anything here." He said.
