>Halloween, a once a year festival where everyone on the island enjoys dressing up
>MC is suddenly startled by Tena yelling Trick or Treat
>Tena is particularly excited as a Jack-O-Lantern Girl and has dressed up as a witch
>MC unfortunately is not dressed for the occasion as he only has his normal clothes
>even Vivi is dressed up though MC feels like he's seen her in that outfit before which gets him a scolding
>when Tena suggests finding something for him, he's reluctant as he predicts it will be girl's clothes
>Vivi suggests mugging a poacher, but MC doesn't want to wear their outfit either
>oh yeah, Tena called them out here in the first place
>seems she wants to host a Halloween party so she wanted them to help prepare which MC is more than happy to
>great, she'll prank him a lot as thanks later
>he'd rather she didn't
>also undead
>apparently they've been interrupting her Halloween preparations for some reason, possibly being disturbed by the lights/decorations
>fending them off, Vivi wonders if the clothes of a skeleton would do
>MC objects as they're barely wearing clothes in the first place
>maybe stripping him would work then which he also thinks isn't a costume
>the undead being undead are relentless however so it seems they'll have to change venues
>the forest is chosen as the decorations/lights can be hung up on the trees instead of left on the ground
