"Diggity Dungeons & All That" is a theme song that the creators of Dungeons, Dungeons, and More Dungeons used to promote a "cooler" version of the game during the '90s until it lost its popularity.
In Dungeons, Dungeons, and More Dungeons, the song is heard during a commercial from the 1990s for the titular game.
I flip the cap back, and roll the dice
Don't step to the wizard
'cause the wizard don't play nice!
