Sticky Beak (Unabridged‪)‬

Rowena Batts has enough problems in her life without adopting a crazy cockatoo. She's just splattered two hundred grown-ups with jelly and custard, and her dad's getting married to her teacher. But Sticky the cockatoo turns out to be just the friend she needs.
Another hilarious book about Rowena Batts, an extraordinary, articulate girl who doesn't let a fact like not being able to speak stand in her way.
