Little goblins, don't you know stealing is bad? Look, I brought you a bag full of glitter and I'm going to kick it all around your camp so it'll be nice and shiny and you can leave those lanterns alone!

I support @Anek 's efforts. I will not assault a creature that has shown no malice towards others, and I think it unfair to judge a different species by my own species' made up rule regarding property ownership. But trading glitter for lanterns is an excellent idea! (And to be honest: I love shiny things too. Dancing in a whirlwind of glitter is fun!)
