Hamma Jamma's Grandfather

Hamma Jamma's Grandfather of an unknown name is a Hammer Bro. brought up by his grandson several times in Paper Mario: The Thousand-Year Door. Quite cleverly on Nintendo's part, he actually first appeared as an unknown Hammer Bro. in Super Mario Bros.

Hamma Jamma's grandfather actually never appears in Paper Mario: The Thousand-Year Door, and may even be dead. However, as stated above, he earned several mentions in that game. These mentions are all the product of his grandson Hamma Jamma's ramblings. Hamma Jamma, a fighter in the Glitz Pit and member of the Hamma, Bamma, and Flare team, continually cites his grandfather as his inspiration. Apparently, his grandpa once owned his beloved hammer, and is one of Hamma's several family members he left behind to pursue a career in fighting.

However, as aforementioned, Hamma Jamma's grandfather did appear in a Mario game of old (Super Mario Bros.). This fact is confirmed by Hamma Jamma's statement of "World 7-1" being his grandfather's "'hood". This is commonly taken as a clever reference to Super Mario Bros., which features a World 7-1 stage filled with Hammer Bros. It is unknown how well Hamma Jamma's grandfather fared during Mario's conquest of World 7-1, or if he still works for the Koopa Troop (if he is even still alive).
