New Super Mario Bros. DS World 3

Has this ever happened to you? The Giant Cheep Cheep in World 3 jumps out of the water ONCE and then stops jumping making it impossible to attack the boss. I keep getting game overs with a Time Over because of this.Does anyone know of a way to force the Cheep Cheep to jump out of the water or what I'm doing wrong and how to make the Cheep Cheep jump?EDIT: Nevermind. As soon as I posted this I went back in and beat the Cheep Cheep. Would an Admin or Moderator please lock and or remove this thread?

Take a mega-shroom into the fight as your secondary item.As soon as the fight begins, use it. When he jumps out, he will jump into you and die. Hope that helps.
