MERVs are generally small fish that pilot flying vehicles. MERVs hover in the air and shoot lasers at SpongeBob or Patrick if they approach them.
In the level "Shell City, Dead Ahead," they are fish under the control of Plankton. They are blue fish who wear red and yellow horizon-striped shirts and a Chum Bucket bucket helmet on their heads. They pilot vehicles that resemble buckets without handles. The fish sits in the bucket's top, along with two levers. The bucket has a flat wing on each side, and on its back is a bamboo tube attached to a bucket, which excretes smoke and fire. On the bucket's bottom is a laser-shooting weapon.
In the level "Welcome to Planktopolis... Minions," they are upgraded of the previous MERVs seen in "Shell City, Dead Ahead." A bamboo handle is now attached to the bucket and a propeller is attached to the handle. The wings are replaced by missile launchers that shoot red firework-shaped missiles. The bucket spitting out smoke and fire now has a rudder and the laser attached to the MERV is upgraded and square-shaped.

Role in game
MERVs are the ninth and last enemy type introduced in the game. They first appear in the level "Shell City, Dead Ahead." They hover above the ground, and if SpongeBob or Patrick approach them, MERVs will target them with orange-yellow lasers before blasting them with a blue laser. The laser can only be dodged if SpongeBob or Patrick move away from the MERVs.
In the level "Welcome to Planktopolis... Minions," they gain missile launchers, which shoot missiles that split into five mini-missiles. These can be spun back once SpongeBob or Patrick's spin attacks are upgraded. Their laser can now push away SpongeBob's Sponge-Bowl via a purple laser.
MERVs can only be defeated via ranged attacks and they take two hits to defeat. The Mini-MERVs give the player 70 manliness points when defeated, while the MERVs give the player 200 manliness points.
