# Drawing Doodads in an External Program Doodad sprites can be drawn using any image editor and saved as .png files (with transparency). You can then create a doodad file from your series of PNG images. Most of the built-in doodads that ship with the game were created in this way. ## Create a Doodad from Images Save each frame of your doodad as a separate PNG image and then use the `doodad` command-line tool to convert them to a `.doodad` file. ```bash # Usage: doodad convert [options] # Example: doodad convert door-closed.png door-open.png door.doodad ```
