It’s "Adopt-a-Puppy" day and Zoe and Harvey host Olive and her father who have come in search of a new family friend. But the puppy Olive falls for does not turn out to be as courageous and Lassie-like as her father would have liked. Zoe relives the first time she met her beloved dog, at the same time as her best friend Harvey, who had just arrived in the valley!

It's Harvey's birthday and his mother offers him his maiden flight in a hot-air balloon. Of course, Harvey instantly thinks to invite Zoe along to share his dream-come-true! While Harvey is over the moon, Zoe is afraid and she shares her fear of flying with Lassie. She cannot however bring herself to confess her fear to Harvey and runs away just before take-off.
