Boxes of Cok O Pops cereal can be found in all of the 24/7 convenience stores, as well as inside several safehouses. Additionally, the Cok O Pops artwork can be found on the sides of an articulated trailer in GTA San Andreas.
In GTA: Vice City Stories it is sold in Fidl, retaining the same design from GTA San Andreas.
The cereal's name is a reference to Coco Pops, while the usage of a cockerel mascot is a reference to various cereal products, like Kellogg's Cornelius Rooster in Corn flakes, or General Mills' Sonny the Cuckoo Bird in Cocoa Puffs.
- On the Cok O Pops box, the Cok O Pops chicken is being choked, a euphemism for masturbation.
