These BGOs are custom. If you don't know how to add custom BGOs to your levels, you must copy all files (.txt,.ini, .png) from archive to your level folder. Then open "Custom" section in level editor and click on "New tileset". This will open Tileset Editor. Then find these graphics by ID, name, or just choose "show custom only" and put them into white squares with your mouse. Type a name for your tileset and click "save".
