They're working out hard at the Turtle Hideout today. Instruct Leonardo together with Master Splinter and the rotating training dummy in the fighting techniques of the Ninja. Afterwards you can experiment in Donnie's lab. Once the Dark Ninja and his loyal soldier trigger the explosion function, it's time to use Turtle Power. Fight on all 3 levels of the Turtle Hideout. With 10 guns and an oven that spits out pizzas. Make it clear to these uninvited guests that they are not welcome in the territory of the Turtles. Once the battle is over, you can fire up the pizza oven and relax in front of the flat screen TV playing a video game. Or climb onto the street with your skateboard and board over the mini ramp.
