Help with my animation...

Hello,

I know this may be annoying, or whatever, but I'm stuck with this project that has to be made in Flash and I simply cannot cope.

I can only do the basics really, motion tween, etc.

I'd like the core of the animation to be this gun shooting one of the crayons.

So I need help with two things I think; How to make the gun appear as if it is shooting by itself? I would like to make the trigger being pulled slightly and the top bit move backwards and then shot forwards to create the shot.

Then I would like to follow the 'bullet' as its flying, so I was thinking of that sort of fuzzy/running background to make the crayon appear as if it is flying?

How possible are these things to do?

Can you please help me :<

Thanks.
