Kodak EK4 Film, Fuji film?

I bought a Koda EK4 on a fleemarket (I think that what it's called in english) for about 1,2-2,4 USD. I also got a purse to keep it in, but it was missing film and the battery was flat (and am not quite sure if it works or not), I know where to get the battery, But as they don't sell the film I need, and this is my first instant camera, so I don't know how to get the proper film, and if there are any. I've heard you can use fuji film, but I'm not sure what size, or if it works.

Sorry, but the Fuji instant film that could be modified to work in a Kodak Instant Camera (like you just bought) has not been available for several years.
