The music in Frogger is taken from a variety of sources, some public domain (such as the Japanese nursery rhyme "Dog Policeman" and the minstrel song "Camptown Races") while others are stolen copyrighted music from anime (the Japanese theme songs to Rascall the Raccoon and Heidi, Girl of the Alps).

Re-releases of Frogger tend to replace all of the music in the game, including certain public domain songs, with original tracks (though "Camptown Races" tends to remain intact).

In the US, the Sega Genesis and Super Nintendo Entertainment System's final official releases in the 1990's were the same game: a port of the original arcade Frogger made to coincide with the PlayStation and PC reboot.

The Twin Galaxies Intergalactic Scoreboard announced a prize on September 24, 2005 for $1,000 to the first player to beat George Costanza's fictional Frogger high-score of 860,630 points, from the Seinfeld episode The Frogger, in which George buys a Frogger arcade-cabinet that holds his high-score on it and ends the episode trying to cross a traffic-busy street with the battery-powered cabinet, ala Frogger style.
The contest ended in December 31, 2005 with no winners, and it wasn't until December 22, 2009 when a person named Pat Laffaye from Connecticut, USA beat the fictional-score at 896,980 points. Pat's highscore was then beaten on July 15, 2012 by a person named Michael Smith, with a new highscore of 970,440 points.
