Adoption as seen through "Miss Spider's Sunny Patch"

There are a few shows Katerina really likes on Nick Jr.: Ni Hao, Kai Lan, Yo Gabba Gabba, Jack's Big Music Show, and Miss Spider's Sunny Patch. They had a great episode on Miss Spider's the other day about family trees which necessarily included the topic of family creation by adoption. Three of Miss Spider's children are adopted (a firefly, beetle and bed bug). While Katerina is only 15 months old and does not understand the topic whether from Kelly and me or a cartoon, I want to find this on DVD for her to have later on in life. It is a cute cartoon without the added benefit of the adoption topic.
