Before I explain the new Dolphin challenge, I just want to mention changes to the Mystery Boosts. They are now called TTTT Boosts and if you buy for example 500 to complete the Cow Villain Challenge you will get new members into your community. They will join automatically and get a TTTT Boost from you. It’s quite cool, you get new members, and they get some crypton.
Since the Cow Villain challenge was quite successful, they will also add a Dolphin Challenge in January. To complete it, you will need to buy a max bulk deal, which will cost $100 (you can’t use Salepoints on them).
The reward is a limited building skin! There will be 5 levels, it will start with rare, and when you buy another one the rarity increases which will change the effects of the building.
