I had a look and that show is simply a ILDA file imported as a show. They may have done that to protect the source frames or other aspects of how the show was generated.
In either case you have the entire generated ILDA file, so you can get to any frame you'd like and copy it or aspects of the frame. I am not familiar with Mamba Elements, but in MIII or Mamba II, you simply choose Frames - Insert Framelists and choose the a_forest.ild file and it will import the entire show as a framelist. After that you can go find your frame and copy whatever elements you want from it.
