That's the new song Nanu has composed.
If you are bored with this song, here's the first song that Nanu composed: "Digbun, digbun, aulay!" You have full freedom to use whatever actions that suit you. But the rhythm should be "Dig-a-bun dig-a-bun, au-lay."
When you sing these songs, don't forget to tell everyone that they have been composed by Nanu.
Three cheers to Nanu!
