We Built This Ballpark is a song sung by The Fluffers while Cleveland and his friends are rebuilding the Stoolbend High School baseball field into Waterman Yards in "Field of Streams". It is based on the song "We Build This City" by Starship. After the opening bars, the song switches to the Starship version. The song, however, is cut short when Cleveland chases away a group of girls softball payers celebrating the return of the field.
