Things that Dangle
When your human shrieks 'ooh, sparkly mushroom! Give me all the shinies!' in public, you're witnessing one of two scenarios: they're a gamer with questionable impulse control, or they've found another dangly thing to hoard like a magpie with abandonment issues. As long as they're not stuffing chicken wings and jello into their bag like some kind of feral raccoon prepping for the apocalypse, count your blessings and let them have their shiny metal mushroom.
