Digi-Koopa

Bowser Memory Koopa Troopas are enemies that appear in Mario & Luigi: Bowser's Inside Story during the battle with Bowser Memory ML. They appear as one of Bowser Memory M's attacks. They look like generic Koopa Troopas but are square shaped and pixelated. When Bowser Memory M finishes his mushroom attack, a Bowser Memory Koopa Troopa arrives and bites Bowser Memory M, shrinking him in the process. Bowser Memory Koopa Troopas do not appear in the remake.

Trivia

 * This attack is very similar to how a Koopa Troopa hurts Mario when he makes contact with it in the recurring games.
