When his mom leaves on a business trip Buster is forced to stay with "Fake" Auntie Pauline her husband and her daughter Polly.
As time passes Buster realises something is strange about Aunt's plant "Pablo".
Later Buster calls the Quike Brothers to help him hunt the monster but after a little misfortune Polly's dad is also hypnotised by the plant.
