The Tale of Prisoners Past

After Janice is bitten by a chameleon at the local pet store, it follows her and her friend Sharon home. The chameleon soon tries to take over Janice's life, following the saying among chameleons- 'Bite you once, bite you twice, a little water, pay the price.' Seems that if a chameleon bites you twice and water touches you, you switch places with the creature.
