A shirt? Cool. An iconic stuffed toy? Nice. A bizarre string of references to random strange animal in particular? Hilarious.
An exact physical duplicate of an established character being INTERACTED WITH.
No that’s fucking dumb.
EDIT: Because @Aspirety needs to get told
Kanon: Nanase Rumi appearing in Yuichi’s classroom(VN and 2006), Peach Juice from Air trucks appearing(Anime)
Air: That stupid Kanon reference(Anime)
Clannad: Akiko Jam(Anime?), the Anteater Plush from Kanon(Anime?)
Little Busters: ANTEATER PANTIES
