Lucy loves her big sister Goosey very much! However, there's one problem... Goosey doesn't think that Lucy is her sister, because Lucy is a dog.

Lucy tries to show Goosey just how good of a goose she is. She displays her glossy goose feathers (made up of leaves), her goose honk (bark), and her nest of eggs (rocks), but Goosey isn't convinced. Will Lucy be able to prove to Goosey that they are sisters?
