The two frogs
Once two frogs fell into a pot of cream. They could not get out of the pot. So they swam round and round and round in the cream.
"Oh, this is the end of my life," said one of them. It stopped swimming and died.
But the second frog swam and swam and beat the cream with its little feet. The cream became a ball of butter. The frog jumped on the ball of butter and got out of the pot!
