Christmas pets, adult to PPS?

I thought there was a year for Christmas where Adult pets designs were released on PPS pets. Am I misremembering something?

Thanks, that's what I was thinking of. I knew it was done once but I couldn't remember what year it was. It's a shame non of the pets were originally growing ones.
