He also looks kind of like Moe otherwise, and tends to act pugnacious in spite of his small size. While he doesn't poke anyone in the eyes as Moe did, he does hold his hands over Batman's eyes with the idea that the Joker can then punch Batman, something that was represented on the cover. The trouble is, Batman ducks, and then the Joker just punches Gaggy instead.
Batman beats the Joker, the same as he had without the involvement of the Joker's new Stooge.
And Gaggy the Joker Stooge didn't live happily ever after.
During the course of the story, Gaggy uses a recognizable Moe Howard line. He says "Why you--!" on page 9. In the original Three Stooges films Moe would frequently say that in reaction to the knuckleheaded stupidity of some of the other characters, frequently responding with violence as well.
