Flounderflage

Flounderflages are red or green flounders with yellow underbellies that appear in Mario & Luigi: Dream Team. In the field, Flounderflages camouflage themselves into the sand, give chase to Mario and Luigi upon sight, and becoming more visible once doing so.

The color of their backs indicates which bro they will target; a red Flounderflage will always target Mario and never harm Luigi, even if it aimed for him. They begin battle by covering themselves in with the sand, thus rendering them harder to see and impossible to identify the color. They can attack by creeping steadily towards a bro then swerving into its target at the last second, which can be jumped over. They may also stand in front of the bro and tackle them. If they point upwards - due to having the other bro's color - they will jump over the bro and miss entirely. If it misses or the bro dodges (but not if they are counterattacked), they attempt to ram the bro from behind on their way back. Additionally, Flounderflages may spawn out of the sand over the course of battle.

Purple Flounderflages are rarer, only found in the Torkscrew battle to attack Luigi from behind while Mario is being chased by Torkscrew's drill.

Trivia

 * Flounderflages camouflage themselves in a similar manner to how Koopeleons do in Mario & Luigi: Partners in Time.
 * They are very similar to Noozes from Mario & Luigi: Bowser's Inside Story, as their color indicates which Bro. they will attack. However, Noozes can switch forms, while Flounderflages cannot.
