The charm on Donut's collar that replaced a butterfly and which she considers ghastly.
The charm gets its close inspection at the Security Checkpoint, where one of the Shade Gnoll Riot Forces guards bends over Princess Donut, takes hold of the collar charm and examines it closely as part of the search. Donut supplies the commentary without being asked: it used to be a butterfly, but now it is this ugly thing, and she knows it is ghastly.
The gnoll lets it go and stands, satisfied, declaring both crawlers clear. Whatever the charm is now, it does not register as contraband.
A charm hanging from Donut's collar, replacing an earlier butterfly design with something she finds ugly enough to apologise for unprompted.
Donut's worn collar enchantment, checked and cleared by security and resented by its owner.
