You decide to go into one of the animal doors. Since snakes are your favorite animal, you go in that one. The room looks like a snake habitat is the zoo, with all sorts of tropical plants and trees. You walk around for a wile and don't see any snakes, so you decide to head back, when your legs feel weird, so you strip down to your boxers, and gasp.
Your legs are compleatly covered in scales! You feel them, and have the weirdest sensation in your life. You start to wonder what's going on, when you notice you toes being pulled in! "Oh, !" you say as you realize what's going on. Your lower half is going to turn into that of a snake! You strip out of your boxers in time to see your member and balls be sucked in! You make a breake for the exit, because if you get out, it might reverse the prossess. You suddenly stumble, and look a your legs. They are fusing together, form the top down. You have to wait until they finish fusing. After a wile you are able to get up and you feel your canine teeth lengthen into fangs, and your tounge split in two at the tip.
You slither around for a wile, and have the weirdest sensation ever. You decide to see what snake your lower half is, so you turn around, and your eyes widen at what it is...
