Grandma Mia

Grandma Mia is a grandmother to Mario and Luigi, who was briefly mentioned by Mario in The Super Mario Bros. Super Show! episode "The Fire of Hercufleas".

After Mario and his friends had helped train the obese Hercufleas back into shape, Mario remarked that Hercufleas was even stronger than his Grandma Mia's garlic chip cookies. However, this was the only time that Grandma Mia was ever mentioned, and no other information about her is known, including whether she is Mario and Luigi's maternal or paternal grandmother.

In the Nintendo Comics System story "Vote Mario for Man of the Year", when telling Toad about his secret pasta recipe, Mario mentions that "only Luigi, Grandma, and me know it!" Given that the comics were produced separately from the cartoons, it is not known whether or not Mario was referring to Grandma Mia in that statement.
