Happy Aquarium: Walrus Referee and Football Seal join the team

Zack the soccer-playing lion cub is now joined by Russ Referee and Diego the Football Fan in Happy Aquarium. Both Russ and Diego are animated critters that cost premium currency to buy. Russ taps his foot, blinks his eyes, and blows his whistle. While Diego is more like Zack, and carries a hot pink soccer ball on his head with which he performs tricks in the tank.

Russ is also a Limited Edition character, so if you've got 24 Pearls or 20 Facebook Credits (the equivalent of $2 USD), you should grab him ASAP, cause he won't be sticking around the shop forever. You can find him under "Specials!" star tab, under the subcategory "Premium", while Diego is with Zack in the "Tank Mates" tab, and goes for 48 Pearls or 40 FB Credits ($4 USD).

Given the game's recent premium currency increase for leveling up, these characters should now be easily affordable for high-level players.

Happy Aquarium: Lady Baba brings her poker face to your tank

In a nod to you-know-who, Happy Aquarium has welcomed Lady Baba to the store. For either 52 Facebook Credits ($5.20 USD) or 62 Pearls, you can have your very own pop icon of the sea, but there are only about 2,600 left as of this writing!

We're calling it now: this one will last for about 37 more seconds, so don't wait. Just don't call her name. Alejandro ruined that for the rest of us.
