If you read it again you will see that he was talking about ecoins pandas. Just another example given here http://forum.eternalmu.com/threads/panda-pet.537476/ even if the question is different.

I told you already that as a new player it's best to buy any exp pets/rings from xShop directly and there you can see that ecoins section mentions the days period while mupoints doesn't have any. Don't buy from other players just because it's cheaper, those pets are pointed mostly for people with rr. Also you cannot see if the pet was purchased with ecoins or mupoints.
