[He's a little puzzled as to why 9S seems so unfamiliar with the pumpkins when he remembers.]

...Oooh, that's right! You came in after the whole festival and Story Eater came in. There were pumpkins everywhere around town.

Yeah, they're a fruit, and can be eaten in a lot of different ways. You can even carve faces into them for decoration.

[You know what let's see if he can find that thing—ah there it is. The person he had randomly thrown it at had left it on the floor, so he'll be picking it up to hand to 9S so he can get a better look.]
