Modeled after the most well-known astromech droid in the galaxy, this R2-D2 holds a 1.75 gallon fish tank in his central compartment. As if a Star Wars themed aquarium wasn't enough, the domed head rotates with any vocal command you issue and he utters his familiar “bleeps” from the movies. His radar eye houses the eyepiece to a built-in periscope, providing you with an intimate view of the aquatic activity below.
Although discontinued in 2008, there are still some floating around out there on Amazon and Ebay, much like when the Millennium Falcon released its claw from the Imperial Star Destroyer.
