A shape changer

Tanya stood up and said," I know what I want my first wish to be". Sarah looked up to her mistress realizing that she had never granted a wish as of yet and hoped that this would not be to difficult. Tanya announced " Genie please let me explain my wish so there is no misunderstanding". Sarah nodded and said "I understand". " I wish to be able to become a shape changer. That I could turn to any animal real or fictional, become a superhero, a tree, smoke, anything and change back to this form as I please' Tanya said exictedly. Tanya added, " I do not want to get stuck as a rock or something like that." Sarah stopped and thought about it for a second and felt the power building in her, she understood that she would be able to grant her wish but because she was new at being a genie this would take a bit of work. " I would like to shrink and grow as i please and ever take the form of water, can you do this my Genie?, Tanya asked. " Yes mistress I can grant your wish but it will take some time please sit down," Sarah said. Tanya sat down on her bed immediatly. "Please open your mouth and inhale," Sarah said as she started to turn to pink smoke. Tanya inhaled deeply. The pink smoke floated over to Tanya and started to enter her new mistress. Tanya coughed for only as second as she realized she now had a genie entering her. Sarah knew if she were a stronger genie she would not have to enter her mistress to grant such a wish but now there was no other alternative.
