The description says: This magical piece of toast just glows, that is all.. Right? WARNING: Feeding this item to your pet can result in your pet being deleted from the database. .____. Can it really delete a pet?!

Neither SHQ or Subetalodge say it does, so it probably doesn't. It's likely because the item ID is 666 and they were being funny.

Ahah ok, I see :D Thank you!!
