Loopable happy light fluffy piece with bright flutes and a bunch of pizzicato strings. You can download an uncompressed WAV format of this piece here (in a lot of tempos)!
Plain old mp3 version is here.

Soundcloud has a longer mix that starts slower, and goes faster. You can put together long versions like this from the WAV format download. (This exact mix is included in the WAV downloads.)
