Wendy's has a frozen treat called a Frosty. It's like halfway between a thick shake and an ice-cream. Frosty Frights are anthropomorphized Halloween themed versions of the Frosty cups. Kind of like the McDonalds Nugget Buddies, or Mayor McCheese and Officer Bigmac.
Hopefully one day your country will get toys of your food mascots. I would love to buy a toy of a fried cricket, or McGutteroilchicken.
