The Book Of Smurf Names (item)

"The Book Of Smurf Names" is a book that Brainy found in Papa Smurf's laboratory in the HERO: The Guardian Smurf mini-story "The Book Of Smurf Names". It contained all the original names of the Smurfs that were recorded on the day of their "births", but unfortunately age has caused most of the pages of the book to become blank, so Papa Smurf is only able to remember the names of a few Smurfs like Brainy (Stephen), Hero (Kakarot), Hefty (Marcus), and Grouchy (Oscar) along with his own original name Jonathan.
