The Grasshoppers did not know at just what time they ought to have the party. Some of the meadow people whom they wanted to invite were used to sleeping all day, and some were used to sleeping all night, so it really was hard to find an hour at which all would be wide-awake and ready for fun. At last the Tree Frog said: "Pukr-r-rup! Pukr-r-rup! Have it at sunset!" And at sunset it was.
