In Animal Crossing
"There's an old saying among some of my contemporaries: "Butterflies are beautiful, yet moths are monstrous." Well, if you were to ask me, I'd say they were all the same! By which I mean disgusting! Truly hoo-rrific, wot wot!"

In Animal Crossing: New Horizons
"The great purple emperor lives high in the treetops and is renowned for its pretty purple-hued wings. Its impressive bird-like wingspan and elusive nature have made it a favorite among butterfly aficionados. But truth be told, the so-called great purple emperor has some not-so-great personal peculiarities. For one...it has two horrid HORNS upon its head when it is in its caterpillar form. For two...it has been known to dine on feces and animal carcasses! Hoo! That's why I call it the Emperor of EWWW!"

When donated, the great purple emperor can be found flying between the trees in the main room of the bug exhibit, being one of the few butterflies not found in the butterfly room.
