You clicked on the dragon tail option and when you did you felt a burning sensation above your rear. You looked down and you witnessed a gigantic tail the size of your body burst out destroying your underwear, and pants in the process. The tail then started burning as bright red scales spread from the base to the tip of it.
You stared at it in awe just on how big it was," Holy shit, I didn't know it would be that big." You said moving it around.
However you enjoyed it nonetheless and you petted it intrigued at what it can potentially do. You then wonder how you will be able to move around with it, because of how big it is. As a result you decided that you either have to change yourself more or shrink the tail. However you still consider the other options given to you.
