Polyomino-Rätsel №128823

" Sleep, my darling, go to sleep!
the house lights go out;
the Bees are down in the garden,
Fish asleep in the pond,
Month shines in the sky,
a Month in the window looking...
for free.
Sleep, my darling, go to sleep!
go to Sleep! Sleep!"
the words of S. Sviridenko.
Music by W. A. Mozart.
