Also. there's a note at the end of the newest update about derps. It reads:
"Note: As of right now, in order to turn your pet into the Derp graphics it must first be an adult! When it is an adult you may change the effect from normal to Derp! From there you can use a Regression Ray on your pet to make it baby/teen and it will have the Derp images for those 2 stages as well. We are working on getting this fixed, be patient and stay with us until we can figure it out!"
