   My animation displays correctly, I'm running it once. The problem is after it runs it leaves the image of the first frame behind. How do I clean this up. I've tried [mgr removeChild:sprite cleanup:YES]; , but then the animation doesn't run.

   Thanks for help.

   AtlasSpriteManager* mgr = [AtlasSpriteManager spriteManagerWithFile:@"animBubble.png"];
   [self addChild:mgr z:3];
   CGRect rect = CGRectMake(0, 0, 46, 46);
   AtlasSprite* sprite = [[AtlasSprite alloc] initWithRect:rect spriteManager:mgr];
   [mgr addChild:sprite z:3];
   AtlasAnimation* animation = [AtlasAnimation animationWithName:@"anim" delay: 0.08f];
   int numFrames = 4;
   for(int i = 0; i < numFrames; i++)
   {
   int x = rect.origin.x + (i * rect.size.width);
   [animation addFrameWithRect:CGRectMake(x, rect.origin.y, rect.size.width, rect.size.height)];
   }
   id action = [Animate actionWithAnimation:animation];
   [action setTag:8];
   sprite.position = ccp(currentTile.position.x,currentTile.position.y);
   [sprite runAction:action];

   Use this code :
   [sprite runAction:Spawn action : action, [FadeTo actionWithDuration : 1 opacity : 0] ];

   Whenever u need to reuse the bubble set opacity to 255.
   i m not sure about yr requirement but I hope this wil solve yr doubt.

   good suggestion, thank you and thanks for the line of code. This would leave behind sprites each time, i'd rather clear them. I suppose i could move it each time i needed it.

   I've noticed there's not enough full code sharing within the cocos2d community, partial tidbits of code that makes it hard to understand or come to solutions for simple tasks(compared to javascript, python, and other languages), feels like that "C" arrogance(or social ignorance).

   i found this method which worked for someone, but I'm getting an error:

   [sprite runAction:[Sequence actions:[Animate actionWithAnimation:animation],
   [CallFunc actionWithTarget:sprite selector:@selector(removeFromParent)],nil]];

   - (void) removeFromParent{
   CocosNode *sprite=self.parent;
   [sprite removeChild:self cleanup:YES];
   }

   "I've noticed there's not enough full code sharing within the cocos2d community, partial tidbits of code that makes it hard to understand or come to solutions for simple tasks(compared to javascript, python, and other languages), feels like that "C" arrogance(or social ignorance)."

   That is complete bs - there is a huge amount of code sharing in the cocos2d community. A lot of cocos2d (RenderTexture, Effects, CocosDenshion for example) is built on code donations. There are at least 4 free games with complete source. Comparing cocos2d to javascript or python is ridiculous - they are programming languages with huge user bases whereas cocos2d is a niche product.
