Bartholomew runs around warning everybody to stay undercover, but the palace servants and guards are soon stuck in the oobleck.
In the throne room, the king, now covered in oobleck himself, orders Bartholomew to summon the magicians to stop the storm, but when Bartholomew brings up the bad news that even the cave is covered in oobleck, the king gets the idea to use the magicians' magic words ("Shuffle Muffle Muzzle Duff") to stop the oobleck. Bartholomew finally gets the courage to tell the king off for making such a foolish wish and tells him to use simple words, like "I'm sorry," instead of magic words. At first, the king insists that he never says sorry, but only after Bartholomew states that he's no sort of king if he's covered in oobleck does the king finally admit his mistake and say "I'm sorry."
Straight after the king says those simple words, the Oobleck Storm breaks up and the sun melts away all the oobleck, freeing everybody in the process. At this point, the narrator states that maybe those simple words the king said were the magic words to stop the storm. After the oobleck is gone, Bartholomew takes the king to the bell tower and the king rings the bell proclaiming the day a holiday, dedicated not to oobleck, but to rain, sun, fog, and snow, the four things that have, and always should, come down from the sky.
