How to Append animation?

Hi all,
here’s an awesome mecha animation by dfinitly off of Blend Swap. I wanted to practice compositing the walk cycle onto tracked footage and I realized I don’t know how to append animated walk cycles.

I have only appended meshes, but this seems a lot more complex. Any help is greatly appreciated! (I also posted this question on Blendswap as well - I will post any answers I find)

OK dumb question…I just have to choose all the correct pieces in the Object folder
