Happy Aquarium: Flounder and Sebastian, is that you?

Say hello to Rounder the BFF and Zeb the Crab. These two new Limited Edition critters look like they took a detour from an audition for a Disney sequel of "The Little Mermaid" into the Happy Aquarium store. I'm betting they're here to team-up with the redhead mermaid Muriel, who made her debut in early May.

Rounder costs 58 Pearls or 48 Facebook Credits (which is exactly $4.80 USD). Zeb is 47 Pearls or 39 FB Credits ($3.90 USD). It takes Rounder 32 hours to reach adulthood, and you can buy male or female versions of it, so if you buy two, they can get some piscine love on and make babies. Zeb also comes with your choice of gender, but like all the other crustaceans in the game, he's not a breeder.
