The CloudRunner Flute is an item featured in Star Fox Adventures. It is a long, spiny, spiral sea shell like flute which acts as a call for young CloudRunners to return to their parents.

The CloudRunner Flute is obtained in the CloudRunner Fortress from the Queen CloudRunner so that Fox McCloud could reunite the five Sons of the Queen. Fox must first quickly scout round the Fortress, dealing with all the SharpClaw who pester the children. If the player eliminates the SharpClaw quickly before the time gauge runs out, Fox will be able to play the Flute and send the Queen's children back to her.

The flute is useless after Fox returns to Sauria's surface as it is not even selectable, yet it returns to the Test of Knowledge, representing CloudRunner Fortress.
