You are presented with a wide range of activities in each area which when successfully completed, will allow you to collect one of these fine creatures.
When you go to the Lorax's Forest, you help some Babaloots by putting the correct number of furballs in their wheelbarrows. When you have the right number in the first two wheelbarrows, you then pick the right number to answer the addition question. (see middle right). And for your efforts you get to collect some fine Barballots for the zoo.
At the "Shapes-On Machine (see bottom right) you are called upon to help Sylvester McMonkey McBean complete a pattern involving shapes and colours to create a proper sequence. For your efforts, you can take to your zoo some excellent Star Bellied Sneeches. (This is a lot more fun than collecting stars). Of course, when you have collected all the animals, you are rewarded with seeing the grand opening of young Gerald Mcgrew's new zoo.
The program has lots of hidden clickables and a variety of play activities such as the Musical Band where you can click on individual band members to hear a tune or play with the Clock Sculpture to learn about time.
