Kung Fu Panda 2

You will get this during the Croc levels. Story related, cannot be missed.

Strategies:

Croc fight#1 – River Shrine, your best bet is to doge him and wait for him to turn red, then push to activate your counter and that will do massive damage to him. Otherwise, wait for him to start spinning, and again dodge him and when he gets dizzy, attack him then with strong attacks. You can also run in and hit him while he stands there taunting you. There is also some food around so no worries if you get hit. You can attack him with when he is stunned, and if you are facing the river it can knock him into the water, quickly ending the match also.

Croc fight #2 – Wolf Hideout, same as before, but added are the cannoneers. If you turn red, push right away and you will take out one cannon tower each time. Use same tactics as before to fight him, just dodge more as you are on a small platform.

Croc Fight #3 – Temple of Clear Water, The Wolf Boss does not really change his tactics much in fights, just changes the surroundings. You are again in a close space, and now you have many minions added to the fight. The good news is there is a refill station here, so use Acu-punch all you want. Use counter a lot as well, as it does massive damage.
Note: after you beat him you will be teleported outside, chose to go back into the temple and then exit to get to the roof.
