Rexx and Jester in the Tale of Two Giants

For some reason, the mayor brought the townspeople out to murder the Great Cheese and Jester. Could be because they cheated at cards. Whatever the reason, they barely escape with their lives, only to be captured by the Black Giant, who wants to make them slaves. Rexx is following them and tries to save them, but that's hard to do when he gets tied up and stuck in a cage. Now the giant is going to kill them all in the morning. Who will rescue them from certain doom?
