The Theme from Rugrats (also known as the Rugrats Theme) is, as the title suggests, the piece of music that opens every episode of Rugrats. In the show's intro sequence, the music plays as the Rugrats are playing around in Tommy's living room. In "The Santa Experience", the music has a different arrangement, using a chord-style organ, and a few jingle bells. Another arrangement of the song was used in the opening of Rugrats: A Live Adventure. Unlike the television version of the song, this version includes spoken dialogue from the Rugrats accompanying their actions.
