Kirby: a cozy fluffy blanket and fruity alcohol.
King Dedede: one of those really nice deluxe charcuterie boards with lots of meat, some kind of book on engineering, a scarf.
Meta Knight: deluxe expensive box of chocolate and sword cleaning kit.

Ooooh there there's so many blorbos to give gifts to!! But, I'll just focus on my top man..

For mk probably something practical like some comfy bat themed slippers, the softest rope I could possibly find and ~lots of head~ a super comfortable bed fit just for him! Pretty much anything he could get good use out of 💙

or something tasty for him to enjoy! I don't think I'm the best cook in the world but, I do enjoy baking quite a bit! Probably would bake him an assortment of cookies especially my favorites sugar, cherry and snickerdoodles!
