Mouser (1987 video games)

In almost every game Mousers usually occur as normal level opponents and are often used as an annoyance enemy in TMNT games, being hard to hit and having cheap attack tactics, but have the tendency to be destroyed easily. However in some, of the video games, far greater Mousers with advanced capabilities appear:

Teenage Mutant Ninja Turtles (1989 video game)
In the first console game, they are featured primarily as enemies in sewers. One of the bosses is Big Mouser, a stationary Mouser that is several times larger than even the player's selected Turtle. It fires beams from its eyes, and is only vulnerable when it opens it mouth to produce another standard Mouser.

Teenage Mutant Ninja Turtles (arcade game)
In the TMNT arcade game, Mousers break through walls and pavement in hordes, and have the ability to latch onto the player's Turtles' arm, forcing them to shake it off with rapid button presses in order to negate its life-draining bite. The game's third boss, Baxter Stockman, drops Mousers from his floating contraption.

Mousers also appear in the TMNT handheld game developed by Konami, and in Teenage Mutant Ninja Turtles: Fall of the Foot Clan.

They would later reappear in Teenage Mutant Ninja Turtles III: The Manhattan Project. A mini-boss was the Mother Mouser, a large Mouser (although much smaller than its predecessor, the Big Mouser, and its successor, the Giant Mouser), which was piloted by a Foot Soldier.

Mousers also appear in Teenage Mutant Ninja Turtles: Manhattan Missions, Teenage Mutant Ninja Turtles II: Back from the Sewers, and Teenage Mutant Ninja Turtles: Turtles in Time.

Teenage Mutant Ninja Turtles: The Hyperstone Heist
Mousers are enemies in the game. Also, the game's fourth stage boss, Baxter Stockman, drops Mousers from his floating contraption.

Teenage Mutant Ninja Turtles: Tournament Fighters
Mousers appear in the SNES version of the game, they can be seen in the background of Chrome Dome's stage.
