Je te tiens par la Barbichette

Barbichette is a mountain goat who should be living in the hills. However, one day, she climbs into a car, then forces her way into Sasha and Lili's home. She settles in with them, like Mom's depression, who then invites herself into their home. While Barbichette breaks everything and eats anything, Mom buries herself under the covers. Will the sisters be able to chase the clouds away from their mother and get rid of this insistent goat?
