Jack Russell is, unsurprisingly, a jack russell!
 
Jack is the new student in Calypso’s class and fits in perfectly with Bluey and the other kids. He lives with his mum and dad and has a younger sister, Lulu.

Jack does his best to be a good boy, but sometimes he finds it difficult to sit still or remember to do the things he’s told by his parents and teachers.

Jack is very good at imaginative play and his best friend Rusty loves to play Army, a game that helps Jack focus and remember. His favourite treat is condensed milk.
