[<fantasy forest>]

you originally were a tested experiment, scientists that payed your parents to test on you and of course your parents agreed and you become a experiment, after a failed experiment or so they thought they put you back in your cell and after a few minutes the injections started to take effect, turning your bottom half into the tail of a snake. the scientists tried to transfer you into another room but the effects were in full effect and your instincts took over and before you knew it you were in a forest, filled with other creatures like you.
