You wait until everyone else has gone, and then you open up the frog's tank, pick it up, give it a good lick and wait.
Suddenly your body feels cold. You feel all the hair on your body receeding and when you look at your skin it's turned green.
Your ears and nose vanish, your mouth and cheeks widen and your eyes turn into bulging orbs.
Your hands have turned webbed and orange, and your feet feel tight. You yank your shoes off and webbed flippers spring out to full size. You also note that your pants are half-mast due to your longer legs.
You have a frog's abilities all right - You're a anthromorphic tree-frog!
