Digital Boo

The digital Boo is a Boo that appears in Mario & Luigi: Bowser's Inside Story during the battle with Bowser Memory ML. It appears as one of Bowser Memory L's attacks. It looks like a generic Boo but is square shaped and pixelated. During the attack, Bowser Memory L gets chased around the room and will always hop over the bros while the digital Boo homes in on him. Mario and Luigi have to repeatedly jump over the digital Boo and the attack will end after a set amount of jumps or until a bro stomps on it. After the attack ends, the digital Boo flies away. It reappears in the battle with Bowser Memory MLX in The Gauntlet. The digital Boo is faster and does more damage than last time.

Trivia

 * This attack is very similar to the Elder Princess Shroob's Chain Chomp attack from the previous game.
