Cancer has paralysed her face and stolen her smile but Annabelle Potts can still issue a heartbreaking video challenge for everyone to join the "Lemon Face Challenge" and help all those "little kids who have lumps inside their heads".
Channel 9's Stevie Jacobs threw out the challenge to politicians outside parliament House in Canberra and the sole Senator to pop down and see the Potts family and do the challenge was Conservative Party leader Cory Bernardi accepted.
Like the Ice Bucket Challenge that has raised millions for motor neurone disease, Annabelle and her family hope the Lemon Face Challenge can take off and shine a spotlight on childhood brain cancer.
Annabelle's favourite band, The Wiggles, were the first to take up the challenge and called on others to join them in sucking on a lemon and posting the video online for charity.
The cancer, diffuse intrinsic pontine glioma (DIPG), only affects children, is 100 per cent fatal and has an average survival time of about nine months.
