The Uoolla Unicorn features over 70 sounds and reactions, including singing, giggling, and blinking. It also responds to feeding and other interactions. Multiple Zoogooz can link together by holding hands, enabling them to hug and hang. The Uoolla Unicorn has a goo-filled body that stretches, squishes, and hugs. Each one contains a hidden charm inside its gooey body, revealing its unique personality when pressed. The ZooGooz collection includes five characters: Uoolla Unicorn, Sensoo Sloth, Mookie Monkey, Koomi Koala, and Duroo Deer, designed for interactive play and collectibility.
