Mati Bustani Wood is 6 years old. In August 2010 he was diagnosed with a medulloblastoma in his brain, while on holiday with his family in Brazil. He had an operation to remove the tumour, and has already made it through 6 weeks of radiotherapy. Now he is starting chemotherapy, all to prevent recurrence.

The corkbots decided to dedicate their Christmas film to Mati and his family. He told them that he'd like to help poor children in Africa.

He and his brother Luca asked the corkbots to tell their friends to donate to Action Aid. Millions of children in Africa are so poor they don't even get to go to school. Please give generously.
