On Thin Ice - It's Willie the Snow Seal's birthday, and there's going to be a big party with singing and a lot of yummy cake. It's a good thing that Emmy and Max brought their skates, because Willy lives in a huge icy cave next to a frozen pond. Zak and Wheezie are excited about the party, too, except for one thing-they don't know how to ice skate! Their friends are happy to help them learn. Although Wheezie is eager to get started, Zak isn't so sure. On their first attempt, they immediately fall on the ice. Emmy explains that they need to lace their skates tighter so their feet aren't so wobbly. Much better! But after a few steps, down they go! The gang advises them to hold onto the branches at first and then try holding their arms out to the side to help keep their balance. Emmy shows them the best way to fall - a very important safety tip. As they practice, they improve, and are finally confident enough (even Zak!) to skate into Willie's cave for the surprise celebration. The Shape of Things To Come 0 When Zak's new dragondisk gets all gooey and sticky in Marshmallow Marsh, the gang learns that the only way to clean it is to dip it in Crystal Fountain in the Crystal Cave. Sounds easy enough, but once they arrive, they are greeted by Kristel, the door that guards Crystal Fountain. Kristel has three shapes below her face: a square, a circle and a triangle. The gang must find items that match these shapes in order for Kristel to allow them to enter. They split up and each group discovers that many shapes are similar to the ones they must find; for example, squares are a lot like rectangles and circles are close to ovals. Everyone learns not to jump to conclusions about the shape of objects until they've been studied carefully. Eventually they discover items that match Kristel's shapes, and at last she allows them to enter. Inside, Zak happily cleans his dragondisk until it sparkles like new!
