How can three preschool friends climb a mountain, star in a circus, fly an airplane or hide inside their own paintings? Why it's easy! With a little imagination, that is. Your imagination can take you anywhere you want to go, let you be anyone you want to be, and, if you're lucky, it'll even create your very own big, big Friend! And that's just what happened to three young friends, Yuri, Lili and Matt. Lili ditches her tea-party-ruining brothers in favour of a grown-up party in her doll house, but as it turns out, a stuffy tea-party is no party at all.
