Salmon (a song)

Knock knock, who's there?
Baaa.
There was a little sheep who ran away from her mother, and when she got there, she missed her mother, so she tried to find the way back home. And she suddenly found it. She didn't find her mother, her mother found her, so that's why somebody went to find his sheepy. (Sheepy is the same word as sheep, but two sheep.)

And the very last part, but not least, Salmon.
