The Wonder Pets travel to the island of Madagascar to save a chameleon from a cuckoo hawk. Along the way, they try new ways of doing things and learn about the concept of camouflage. When Ming-Ming pays a visit to Tuck's cage, she messes with his things, causing him to declare he's not speaking to her. Not impressed, Ming-Ming begins a silent treatment of her own. Nevertheless, the two must still work together to help a platypus stuck on a river in Australia.
