The Wabbit and Lapinette fled through the museum. At last, they got to a window, but the sky was a lurid menacing blue. They looked round. The clocks seemed to have peeled off at the door to the exhibit room - and had given up their pursuit. But worse was to come. A giant snail like thing with wiggling tendrils stood in their way. "I'm an ammonite," it boomed. "I'm in charge of skies." The Wabbit faced him down. "I don't care what religion you are. Return our sky to normal." The Ammonite laughed. "That's no fun. What would the denizens of Rome do without me and my wild friends?" Lapinette also stared. "Quite well, I think," she snapped. The ammonite waved his tendrils. "We're essential to the humour ecosystem." The Wabbit suddenly laughed and began to fall about. "Ho ho ho!" Lapinette joined in. "Ha ha ha!" The ammonite scowled. "We're not funny ha ha ha. We're sophisticated!" But the Wabbits wouldn't stop laughing. The ammonite turned and slithered up and down. "I'll report you to the humour council." The Wabbit thought that was really funny and imagined their meetings. He looked out the window. The sky was returning to normal. "I'll introduce you to my friends." The ammonite looked sad. "We can't leave the museum." Lapinette sighed. "Who says?" The ammonite thought and thought. "I don't know. But I yearn to swim in water and eat plankton." "Perfect," said the Wabbit. "I have an idea."
