hello adrian. i just looked over the code. you've got it all running 99% 
correctly. too bad it's that last 1% keeping us from seeing anything.

the problem is, there are no sprites inside the "render" group. this is 
pretty easy to fix, and there are two main ways to do it. i see a lot of 
the "chimp" example in here, so there's only one small change needed to 
make it work like chimp.

the sprite objects in the chimp tutorial keep a class variable of all 
the groups each type of sprite should belong to. you also do this in 
your code with:
     Gun.containers = render
     Bubble.containers = render

the thing you're missing is passing this value to the sprites when you 
call the Sprite.__init__ function. for example, change the line in 
Gun.__init__ to:
         pygame.sprite.Sprite.__init__(self, Gun.containers)

do the same for Bubble, and the sprites will be added to the group when 
they are instanced. currently it seems you only have one sprite group, 
so you could just make "render" a global, and pass that when you call 
Sprite.__init__? but if you start adding more groups, your current way 
is more flexible.

also remember you can easily add and remove sprites from groups with the 
add() and remove() methods in each class.


heh, there's a couple other little things, but i'm sure you'll get those 
cleaned up quick once you can "see" what's going on :]
