Coo carrying Kirby through the skies ofBig Forest.
"Coo's Theme" is characterized by fast percussion paired with a steady main melody containing several long-held notes. The song can be said to bear a more "serious" tone than either "Rick's Theme" or "Kine's Theme". The song itself is fairly quick, and runs in a 4/4 time signature with two main verses of equal length and an introductory non-looping verse which is half the length of one of the main verses.
"Coo's Theme" first appeared in this game, along with the character it is named for. The song plays whenever Kirby is paired with Coo while in a standard stage, and overrides the stage's main theme. The song does not play in boss stages,Bonus Chances, orlevel hubs.
A slow and calm remix of "Coo's Theme" plays in theDeploy the Kirby Tank! stage inYellow Dunes, when Kirby doesn't have theKirby Tank transformation. This version is named"Crossing the Sands".
A different remix of the theme can be unlocked by collecting one of theTreasure Chests found in theGondola Ride stage, to then be played in theMusic Room. It features a longer intro, and the main melody is played two times, each one with different instrumentation.
"Coo's Theme" can be heard at the end of the track "Kirby's Dream Land 2 Animal Friends Medley" from theKirby 25th Anniversary Orchestra Concert. It is once again paired with "Rick's Theme" and "Kine's Theme". Notably, this version of the song is characterized by its loudness, focusing primarily on high strings, and has a new ending verse to cap off the track. The medley is arranged byShogo Sakai.
