Bubble Bobble Part 2 Game Manual

According to the NES version’s manual, this game stars Bub and Bob, the original duo. On the game’s back cover, they are also said to be Cubby and Rubby, Bub and Bob’s descendants.
As seen in the game intro, Bub, and a girl named Judy, were sitting in a park. Suddenly, a floating skull character, who is one of the Skull Brothers, captures Judy into a bubble, and sends her and Bub into the air. Two characters named Drunk (from the original Bubble Bobble) follow the skull and take Judy away. Bub turns (or is turned) into a bubble dragon and heads off to rescue his girlfriend. There is also a two-player mode, implying that Bob has suffered the same events as Bub had. However, the manual states that Judy is a friend of both.
