Usagi Papparanpappa (うさぎ パッパラ ンパッパー) 

Usagi Papparanpappa is a song from "Kaguya Shima Densetsu" and its kaiteiban. However it does not appear as a separate song in either the original musical or on the album. This song is in actual fact the last verse of 'Hyouchaku Shita Keredo...'. However in the "Natsuyasumi! Houseki Tankentai" kaiteiban, they appear as two songs in different parts of the musical. The two parts of the song have very different melodies and serve very different purposes to the musical
