Savannah had a tendency of climbing on furniture, especially the pool table. She refused to listen to her parents and do as she was told. She was aggressive towards her sisters and niece Krissy, and also teased them.
Savannah also had a very big attitude. For example, she talked back to her parents, whinned, and called her family members innapropriate names, and said sorry in a rude tone during her time-outs. She was sent to time-out three times throughout the episode.
Also, Savannah was diagnosed with Asperger's, ADHD, and ODD (Oppositional Defiant Disorder), which is probably the reason for her misbehavior. This was not mentioned in the episode. She was 10 years old on Supernanny, and now she's 17 years old.
