"You mean I have to look like you?" You asked as the wave of warmness spreads over your body.
"Oh of course, just look at you, you don't look nearly genie enough!" The tiger said as your body is forced to stand up. You're pulled more off the ground as your feet expand and grow. There were no shoes for you to rip by your large paws, holding your body weight. Already your body's covered in fur of all tiger-like colours, orange, white, and black.
A tail squirts out from your back as you continue to bulk up. You look a lot like you could potentially pass as this genie's family member, at least you would except for one thing, the tiger head. But when you think that, your face already begins its change. And like the genie, all of your clothes conform.
"Wait you mean I have to look like this?" You ask when your body is under your control again.
"Oh yes, this way they can pass as a genie, specifically a relative of mine. You can see genies in their true world, now then, you final wish?"
"...I wish to go to your world!"
"Granted!" The genie says as you two vanish into nowhere.
