(I have 3 of these)
I've had these little guys sitting in my account for a while, and I just noticed them again and realized they STILL haven't grown yet.
The poor things. They're from way back in December, and don't say PPS, so I'm guessing they're still "growing". Sorta? Maybe? Did their adult outcomes get forgotten in the holiday rush and never implemented? (I noticed they're in the CS archive, but they're not listed as PPS there either, just the pup outcomes listed.)
