Let’s Get It Started . . . The Bronx Zoo has a green lizard, a red crocodile, and a purple monkey. They are the only animals of their kind in existence. One violently windy Saturday, their name tags blew off, and their keeper’s journal was torn to shreds. Inasmuch as they were to appear on television at 7:30 Sunday morning, the night watchman had to replace their name tags. He managed to piece together the following information from the mangled journal: 1. Wendy cannot get along with the lizard. 2. Katie playfully took a bite out of the monkey’s ear one month ago. 3. Wendy never casts a red reflection in the mirror. 4. Jody has the personality of a crocodile, but she isn’t one. Match the animals with their names.
