Reading the description, it’s a bit of promo alongside the new ice cream flavour being launched in the area.
Interesting that they’re doing something that isn’t Gangsta Granny related all of a sudden, as I’ve heard (no citation*) that the reason we haven’t seen any expansion is because Harper Collins didn’t want the land to expand beyond the Gangsta Granny book. So if the IP is up for renegotiation, this could also be used as a method of gauging interest in the brand and if there’s room for growth.
