When I Grow Up - Sally and Nick are trying to guess what they'll be when they grow up when the Cat drops in for a visit. Cat is sure Nick and Sally will never guess what his friend Puggle will be when she grows up. When they see her, they start guessing right away! A frog? A duck? No, a beaver! They discover that, while Puggle may have some similarities to other creatures, she will grow up to be a duck billed platypus! Doing It Differently - Nick and Sally can't seem to find Harvey the guinea pig. They find the Cat in the Hat instead! Cat suggests that Sally and Nick might find Harvey by meeting three friends who always do things differently - like a bird that runs instead of flies, or a cat that swims, or a fish that walks on the mud! Nick and Sally are sure to find Harvey now - by doing it differently!
