Create a new pet and choose whatever desired for steps 1 through 3. When you get to step 4, set all the sliders to the minimum or maximum setting, except for the ones in the "ears" section. Do not click the boxes at the top that change the pet's appearance to a default setting. When you have set all the sliders, go to the "ears" section. Click on one of the boxes at the top that change the ears to a default setting. Go back to step 3, then go to step 4 again. All the sliders will be reset to the normal position, but the changes you made will still be there. By doing this numerous times, pets can become incredibly large or thin, and they can also obtain strange features.
