"Got it!" is a speech bubble used in Professor Layton vs. Phoenix Wright: Ace Attorney, Phoenix Wright: Ace Attorney: Dual Destinies, Dai Gyakuten Saiban: Naruhodō Ryūnosuke no Bōken, and Phoenix Wright: Ace Attorney: Spirit of Justice.
In Professor Layton vs. Phoenix Wright: Ace Attorney and Dai Gyakuten Saiban, it is used by the protagonist (Phoenix Wright and Ryūnosuke Naruhodō, respectively) when pointing out a specific detail in a piece of evidence. In Dual Destinies, it is used by Wright, Apollo Justice, and Athena Cykes when pinpointing an unusual emotion or pointing out the cause of an emotional overload in the Mood Matrix. In Spirit of Justice, it is again used by Justice and Cykes for the Mood Matrix, but Wright uses it when pointing out specific details in a piece of evidence interchangeably with "Take that!"
