For those of you who have read Tove Jansson's Moomin books or heard of them. This is a song called "Oh, tiny party-goer," and I believe that the lyrics are by the author herself. A rough translation:

Your paws are tired
And you can't find the way home.
The idea is that this is what happens after an overlong party.
This is the version I like the best of those available on the net:
