it is just a common glitch that ii find happens when you havent been on for a while and the first type of pet (say piggle) all those types of pets appear to be piggles. my first time with this was with my wraith mixes i couldnt tell the difference between the ice wraith and fire wraith (forgot the real names to them) they both looked like normal wraiths. next time you logg in it should go away.
