Zynga missed the boat for Cinco De Mayo. Last time I checked, it was 4 days ago. Feline Mystery Bags have disappeared from the Free Gift Page all existing ones have been converted to Sombrero Mystery Bags.
The rules of these special bags dictate that they are good for 48 hours from the time they were sent. If you have Sombrero Mystery Bags in your ZMC, it’s because they are converted Feline Mystery Bags. If they were sent less than 48 hours ago then they will be active. If you already opened 20 Feline Mystery Bags, you will need to wait for the next gift reset.
The special loot item was added to the inventory. The Sombrero Hat has stats of 114/150.
