title: Is it possible to add sounds and effects to an animation plist in Cocos2D
body: <p>I am new to Cocos2D. I am working with a couple of people on a interactive "book" with a few small games for young people (below 4 years) that can not read. 
  I started by building a background (Cocos2D) and am able to add Sprites (using SpriteSheets, and TexturePacker) and animate those with use of plists. I wonder if it is possible to add sound-effects in the plist. For example: one of the Sprites has an animation "screaming". It would be very nice if the corresponding sound was incorporated in the plist! This also enables the animations and sounds being created by the more artistic people.
  My experience is to small to write this code all by myself.</p>
