Finchen tells Waldi that when he are looking for a forest all he needs to do are to look for a place that have many trees. Waldi thinks that sounds very smart, but what does a tree look like ?
Finchen describes a tree to Waldi, by telling him that a tree have a large trunk that points up in the air and Waldi goes looking for such a thing. Waldi finds a broom on Nils' truck that fits the description. Finchen then adds green to the description and Waldi quickly concludes that the Sesamstrasse sign must be a tree. Finchen descripes a tree again for Waldi this time in more detail than before and then leads Waldi to the Sesamstrasse forest. Waldi are excited to have finally found his very own forest.
Finchen and Waldi sings a song about how wonderful a forest are. After the song Wadli thanks Finchen, but before he leaves he tells Finchen that her leaf pile must have come from the trees and thereby she protect the leafs and then leaves. Finchen then wonders if that would make her a Blattschrat.
