This is also a Mahoromatic parody. In one episode Vesper sent her a secret weapon (a bra that made her breasts appear larger. When she had to activate the weapon she eventually had to say, "Boobie Missiles!" Two rockets then shot out of the special bra she had been given.
What exactly is the connection between Ritsu and squirtles, anyway? He gets associated with them a lot. At thought at first it was a seiyuu joke (like how Ruko's voice was listed as being by Hikachi Yuu -> pikachu) but it's not.
Shortly after I posted that comment, I recalled something I'd seen in the past -"ZENIGAME" was the pseudonym CAFFEIN used when doing the official art for Ritsu (as seen on his mock-up profile during the hoax.) I couldn't believe I'd forgot. Well, the "second form" part is news to me, at least, so thank you. I guess I never thought to translate his full profile. Oh, those crazy Vippers.
