This is Sumatra, a giant albino Burmese python. She works with Redding Reptile Parties, an event service in Redding, California that brings reptiles to parties. In this video, Sumatra enjoys a hot summer day in the pool with two young friends.
Don't worry about the girls! They're safe. Corey Williams, Sumatra's owner, describes how gentle she is:
She has been to over 500 birthday parties and many schools, she has been around kids since she was a baby, she has never killed anything she even likes our dogs and cat. funny story I have found the most humane way to kill a rabbit or chicken is to give them a strong hit to the back of the neck with a hard object this normally kills them instantly for I don't like to see any animal suffer. Anyway I came in later to see if Sumatra had eaten and the chicken was walking around her cage, she would not touch it unless it was dead so I killed it for sure this time and she ate it right away.
