On Friday Rainbow is attending a party at the zoo - costumes optional. So of course what's Rainbow's favourite animal - a bilby.
Look at these babies aren't they adorable. The weather's likely to be in the high 30s so know full on fur. Though bilby's survive very well in the desert - though their days are spent deep in their burrows.
For a long time Rainbow loved Alison Lester's series about the five kids. In "Clive eats Alligators it goes through what each child wears - stripey pants, overalls ... and Tessa wears a tail. So here is Rainbow's bilby tail and ears...
Oh and here's my own baby bilby.
