Ice Cream (item)
From the Super Mario Wiki
The Ice Cream is an item in the PC release of Mario's Time Machine. It was made with peanuts and was the result of George Washington Carver's various experiments with peanuts. It is given to Mario after he travels back in time to Tuskegee circa 1915 by Henry Ford, who tells Mario to try it out to see if he likes it. Mario does not eat the Ice Cream himself; instead, he gives it to one of Carver's students, who tells Mario that she has been studying to the point where she does not have the time to eat, making her a bit grumpy. After receiving the Ice Cream, she thanks Mario, recognizes it as being made from peanuts, and continues to talk about Carver and his peanuts.
