Afterward, they are confronted by genetically mutated beings. Afterwards Stockman develops for the Foot Clan invisible foot tech ninjas to capture Raphael, forcing the Turtles to rescue him and Donatello to use a cloaking device detector to properly fight the invisible ninjas. At the surface, he is confronted by Purple Dragon thugs, and meets Casey Jones, who equally hates that gang. Afterwards Michelangelo gets on Raphael's nerves, making Raphael leave to the surface. Eventually the Turtles trace the robots back to Baxter Stockman's factory, where they save young April O'Neil. Shortly after a group of mouser robots destroy the Turtles' old home, they begin to attack their new home. Raphael uses his sai to climb walls and has a motorcycle racing minigame riding the Shell Cycle against Casey Jones. Donatello climbs pipes and has a shoot 'em up level using a hang glider. Michelangelo can wall jump, and rides a skateboard through the sewers. Leonardo can crawl through small spaces and rides the hovercraft Sewer Slider for a rail shooter minigame. After the player chooses one of the Ninja Turtles, each of whom has a special ability, the character enters a set of four acts, one of which is a vehicle-riding minigame.
