No more injections

Nina was afraid of injections and thanks to her babysitter, a witch, she was able to avoid them forever. When came the day of going to the doctor, she casted a spell which her babysitter had teached her. So she swapped body with her dad Jason saying him that if he will take the injection instead of her he will back in his body. Now Jason is in the doctor room in his best jumper waiting that all comes to the end. The only consolation for him is that after the injection the doc has promised him a candy.
