Happy Aquarium: NEW! Limited Edition Submarine Transformitron
The Super Cool Submarine Transformitron is a new Limited Edition Happy Aquarium item that transforms from a submarine into a swimming robot. You can buy it for either 66 Pearls or 55 Facebook Credits (exactly USD $5.50) while supplies last, or until May 18th at 6:00 p.m. EST.
While there's no examples on whether it's animated, the above images of the sub going into robo alt-mode support this idea. For something costing 66 Pearls and with no functional benefits, it better be!
