Hi I need an atomic mushroom cloud animation for my game.

Because I'm not good with drawing  I feel free to ask here

the animation should be 2-4 frames and 64x64 pixles black white (no grayscale)
Thought it may be smaller 
By the way there is no need for the cloud to rise out of the ground

Thank you for your try in advance
and of course I will credit you in my game if I use your sprites

If it wasn't for the whole hassle of dealing with Line() commands and window dimensions, I would have tried to grab the nuke animation from The Reign of Legends 3, but sadly it isn't very practical and small in its current state, plus it's kinda not very detailed, since it didn't use a single sprite. Also it doesn't really look that much like a mushroom cloud lol. (see 2:45).

What kind of programming language do you use? Do you just need the images or should they be in a specific format?

I use Axe and I just need the images. 
I thought of an explosion (screen turns to white) and after that there would be the cloud.
It shouldn't grow anymore but it would be nice if you can see the material rising.
Maybe like this one
