There's a super party in town but if you're not wearing the right backpack you can't get in. Some kids, including Yo and Yo weren't able to find the right one. Maybe there is another solution! / It's hard to appreciate what we have. The lizard, for example, is always unsatisfied and believes the other animal's houses are more beautiful than hers. But in the end, maybe she will realize it's not exactly like that!
