DRDSS To make all recovery items pizzas (for Michelangelo)

Building relationships - Once you reach the level where you can use all four turtles at once, you must begin to build relationship with your brothers. Do this by using your brother throw but, take turns who is doing the throw. For example, Leo throws Ralph and vice versa, Don throws Mikey. Successful brother throws will build their relationship then you can use their double team attacks. However failed throws will make them mad at you, and they will go away and you must win their trust again. Raphael tends to be the one that you make mad most often

Defeating the Shredder - In the Boss fight where you must defeat the Shredder, instead of focusing on the many Shredder clones, try fighting the real Shredder. He just stands still while his clones fight you. One attack that works well is Don's team move that shocks any enemy near its radius. Approach him close and use it. It will shock the clones and him, and he will not be able to attack. Change to Raphael because he fights the hardest and attack the Shredder a few times until he recovers. When he recovers repeat the steps until he is defeated. After this level the Foot clan, use a similar tactic when a Foot commander calls in more Foot ninjas as you defeat them. Use the same tactic on him. If you do not he will overwhelm you with hordes of Foot ninjas.
