I found more Roman's World lost media in a folder containing .fla files, screenshots and scripts.
Here it is!

I want to add some more information about these images and script.
The stick thingy standing next to Tom in the Bob gets a job photo was added as a joke and I decided to screenshot it before replacing it with me/Roman instead.
The chiptune music that plays in Bob gets a job was supposed to be the DuckTales NES Moon Theme.
