Book: Ivan the cow's son

Not on the sea, ocean,
Not on the island of Buyan,
Lived was in the old days...
I better not start!
Lived-were the grandfather and the woman
Eating cereal with pie...
There is, perhaps, this little,
Yes, and the tale of another!
As in the days of the king of Peas...
(It seems not bad!)
In General, it was of old:
He lived in the world of Petro-king.
