You will start on the lower level of the big wand and have a large area to work with. When the fight starts, Crocker will be shooting Wish Stars that follow you. Hopefully by this you point you have upgraded Danny Phantom's Ghostly Wail to the highest level, as it is the most effective against Crocker. If you are playing with another player, have them use Timmy Turner because of his long range attack. However, make sure that you are always pointing at Crocker or you will lock onto the energy poles. Once you lock on to Crocker with Danny, he stays locked on as long as you keep the attack held. It is also helpful to have another player there to keep the Grunts off your back. After you drain Crocker's health, use Timmy's Freeze Glove to freeze an energy pole and use Danny to punch it. If you are fast, you may be able to get two. When you destroy the four poles, you will go up a level and must destroy four more. By this time, Crocker will start using the energy draining Wand Bombs and the Toy Bomb which turns you into a Grunt if you are hit. The last level is smaller than the first two, and the energy poles are harder to reach.
