What does killer Kane needs from Iggy freak the mighty?

In the 2002 comedy film "Igby Goes Down", Killer Kane does not need anything from Iggy. However, it is likely that you may be referring to a different film. Killer Kane is a fictional character in the 1985 crime film "The Last Dragon", while Iggy Freak the Mighty is a character from the 2002 comedy-drama film "Igby Goes Down". If you specify which film you are referring to, I may be able to provide you with more information.
