Wild-card
- For answers to commonly asked Wild-card questions, see below.
A wild-card is a very rare pinata that is created while performing a regular romancing process. This is not an evolution of a species. Wild-cards are purely random, and any egg has a chance of being a wild card. The only thing that can help your chances of a wild-card being born is if one or two of the parents themselves are also wild-cards.
Leafos Talk
According to a rumor from Leafos, "On really rare occasions, special pinatas are born. They look different than normal and are a sign of good luck."
When a wild-card is born, Leafos will say, "That's Amazing! There's a one in a million chance that a wild - card piñata is born! It must be your lucky day!"
Special traits
Your rare pinata will have some physical trait that will differ from the rest, e.g., a Moozipan with horns.
Every species has a wild-card version with a larger base value which is increased by 10 times.
Wild-card Hall of Fame
A wild-card is a very rare pinata that is created while performing a regular romancing process. This is not an evolution of a species. The chance of hatching a wild-card is based on skill in the romance mini-game.
Special traits
Each species has three different wild-card versions, with their own physical traits that will differ from the rest, e.g., a Tigermisu with fangs, bushy tail, or mane.
The base value of a wild-card is ten times as much as a normal pinata of that species.
Romance mini-game tips
You can breed Wildcards once you have six pinatas of that species in the garden and are going for a seventh/Master Romancer. When you go into that mini-game you'll notice that all the hearts are flashing. You need to collect all of the hearts before the time runs out to get a Wildcard.
To receive twins, you need to complete the mini-game within a certain time limit. To receive a wildcard, you need to complete the mini-game whilst collecting all the flashing hearts. To receive wildcard twins, you need to complete the mini-game within a certain time limit and whilst collecting all the flashing hearts.
Obtaining all three traits
Everyone can romance to get the first (Classic) trait. To get one of the two remaining traits, romance two wildcards (and collect all the flashing hearts).
Those are the only two traits that you can hatch -- you can't get the third trait on your own by romancing. You have to trade, scan a PV card, or use co-op with a gardener who is able to hatch the trait that you can't. (Since you can hatch one of the traits that they can't, this is a great way to help each other out to get all three traits.)
There are no wild-card versions in Just for Fun mode, because you can't play the romancing mini-game.
It's unknown how to get wild-cards on Pocket Paradise.
For Classic, the odds are 1 in 10,000. (Shared in a Rareware Archives interview with James Thomas given on Viva Piñata's 5th birthday.) View thread
Does hatching an egg with a Cluckles increase (or decrease) the chance of getting a WC?
No. The only thing that will increase your chances of getting a wild-card, is if one (or both) of the parents are wild-cards. View thread
