I know that nobody has found one but it said it was loading and i'm not asking someone to tell me I'm just asking for a hint towards the second pet Also did you notice it showed up on the loading just before the golden piggle was made
According to the wiki, no unique hybrids are known for the Golden Piggle. Nor the Zombie. I couldn't even find the Zombie Piggle in the first place.
You won't find a Zombie Piggle in the Wiki until someone confirms it. Nor will any of the parents and unique hybrids show up in the Wiki until someone confirms it. Either no one has done the right combination of hatching yet, no one has reported in a public place yet, or the associated parents are not in the game yet (the loading icon may be a place holder for pets with the next expansion and possibly use the Golden Piggle from this expansion).
We won't know until enough folks attempt the right combination of hatching (or possibly the right drop/KI Free Games!!!!)
When I picked up all my stuff from my house I went to the pets icon in the attic and clicked on my golden piggle. It didn't look like the golden piggle, it looked like a ZOMBIE PIGGLE. So maybe its a glitch, or possibly a clue that the zombie piggle is out there, waiting to be discovered... Or most likely a glitch.
