Suggestion: So the server I'm actively using Tatsu in has a little in-joke of responding with a Cookie Monster gif when given a cookie. It just now prompted the idea in my mind of cookies occasionally getting stolen by a "cookie gremlin" (copyright avoidance). It could be something like a 1% chance, just for fun.
*Reason: No other reason than the simple joke of a tiny chance that the cookie you're giving to a friend gets stolen in transit. If the giver bought the ability to give more than one cookie, say 5, maybe they all get stolen, maybe 4 end up getting delivered. Regardless, just a fun little random event to spice things up.
Images: [Attached example image. Obviously could be made much better.]
