Bestselling Mothball is back -- with birthday cake! (Carrot, of course.)

She eats, she sleeps, she scratches. But today it's Mothball's birthday and it's time to celebrate!

Created by author Jackie French and illustrator Bruce Whatley, Happy Birthday Wombat is a very funny picture book about enjoying a special day -- as seen through the eyes of the world's most famous wombat.

PRAISE FOR DIARY OF A WOMBAT AND OTHER BOOKS STARRING MOTHBALL

'French and Whatley have conjured an affectionate, believable wombat self-portrait' -- The New York Times Book Review

'I absolutely love the tone of Mothball's diary entries -- the dry brevity and classic wombat behaviour that's made this gorgeous creature an Aussie literary treasure. Whatley's divinely funny illustrations yet again make for an all-rounder of a book that will loosen smiles on readers of any age' -- Kids' Book Review
