The Cocodile was a chocolate covered twinkie
The Chocodile mascot was Chauncey Chocodile, but Hostess has removed him from packaging and the Web site in recent years. Also, since the late 1990s, Chocodiles are no longer sold on the East Coast of the United States. Hostess has only a few West Coast factories making them and to ensure the products' freshness, Chocodiles are sold only on the West Coast.
There has been controversy as to whether a chocodile is a chocolate covered twinkie or a facsimile. The controversy arose due the seeming "texture difference" between the twinkie and the chocodile. During a taste test and debate in Vacaville, California, it was split among those taking the test, as to whether the taste of the cake was the same or not. This issue was resolved however, during a show on the Food Network. It was confirmed by Hostess that the chocodile was in fact a chocolate covered Twinkie. This has caused consternation for some who continue to swear the cake is different.
In actuality, it's the chocolate that makes the difference. Due to the chocolate coating, the cake tends to stay more moist, provided for the slightly different texture when compared to a normal Twinkie.
