Let me introduce you all to my puppetsona, Errand Puppet! Errand or Err for short (ref to ERR message in series, pronounced like 'air'). His main purpose is to be a self-insert PRETTY MUCH LOL as most people need, but he's also an assistant for William Afton. Because y’know. Gotta have lore right.
Is metaphysical in the digital sense, can ‘glitch’ in and out of reality and the digital space. Leaves glitchy presents around in an attempt to spread ‘influence’. Has an internal music box that lures children and puts them to sleep.
