Oh, so yummy....
Super Mario Cookies are epic cookies that first came out in the 1600s. They were made due to Mario's rising fame in Mushroom Kingdom and around the UnWorld. They are still very popular, but as they are several hundred years old, they are a little stale.
Though it is obvious Mario was very famous when Super Mario Cookies came out, there was another reason. The Tubby Toast was becoming popular, and this was very very very very very very very very very very very VERY bad. So, they made these cookies to take care of the problem. Tubby Toast was eventually considered inferior to Super Mario Cookies, and now the Teletubbies are mad, and can't do anything about it.
Super Mario Cookies come in several flavors, some of them better tasting than others. Some of them make me want to throw up. Others make me shoot into the air for no particular reason. Then there are some that taste like crap, but in a good way.
