Import animation to scene

I have a character that idles in 4 frames and a scene with waterfall animation in 4 frames too. How can I bring my character over to that scene while keeping the animation. If I do a simple copy and paste, they get put side by side so it becomes 4 frames of water followed by 4 frames of my character idle. How may I go about this? Thank you!

I think what you are doing is selecting the entire frames, which means you are pasting the frames at the end of your animation.

Make sure you have a layer for him in your scene. But just select only him in a single frame(not the background). Hit ctrl+c and then go to the desired frame in your scene and hit ctrl+v to paste him. You will then have to position him.
