I've been seeing posts in the Sylvesti sales forum advertising for 'wheel pets'. Or 'event pets'. What are they?

Hey there Somewhat.

Wheel pets and event pets are special "Tagged" pets that are available during festivals. They have preselected color palette's as well as their "tag".

Wheel pets can be won by spinning the festival wheel, but you need wheel tickets in order to spin. The 2-Vis and 3-Vis eggs on the wheel's are very rare and hard to get, which makes wheel pets very valuable. They can sometimes be won in egg auctions and through the "Wheel Raffle".

Event pets can be found and captured in the wild during the festivals. They're a lot more common then wheel pets and easier to obtain with the exception of the wild themed Nephini which are incredibly hard to find.

They always have in purple letters saying what their theme is. You can also buy them from other people. And I think if you breed a male and a female of the same theme together you get another theme pet of the same theme.
