Singer Justin Bieber is auctioning the snake he brought as his date to the 2011 MTV Video Music Awards to raise money for charity.
The teen star posed with a baby boa constrictor on the red carpet at the Los Angeles prize giving in August, telling reporters the pet's name was Johnson.
Now, he's donated the reptile to a celebrity auction and will hand over the proceeds to Pencils of Promise, an organization which funds schools in the poorest parts of the world.
A message on the CharityBuzz website warns fans, "Keeping a pet snake is a long term responsibility. Before making any decision about keeping one, please ensure you have the money, space, knowledge, time, resources and enthusiasm required to properly care for the species you intend to keep, for the duration of its life."
The winner must also guarantee necessary veterinary care will be provided.
Johnson is expected to fetch $1,000.
