Rotorua boy Elliott Crimp tells people he has "ninjacoccal" disease because the ninjas got into his blood to beat him up from the inside.
The 4-year-old was going to paint a ninja yesterday, but it turned into a bit of a red blob so he did an abstract painting with handprints.
Elliott's work, touched up by artist Marcus White, will be auctioned at a gala next Thursday to raise money for Kidz First Children's Hospital in Auckland where he's lived for the past seven months.
He's celebrated Christmas, his fourth birthday and Easter in hospital.
Since contracting meningococcal B at the end of September, the Rotorua boy has endured more than 60 operations and has lost two fingers, part of his right foot, areas around his knees and all his toes.
