"Robot Cowboy" is a song sung by BMO in "Angel Face." It is sung while BMO role-plays as the cowboy Angel Face and rode on Jake in horse form in the desert. He describes that being a cowboy is lonely but that he needs to do his job and protect the baby piglets. The Cactus Guy is also introduced in this song.
| (hums melody)|
Being a robot cowboy,
Is a lonely job.
But somebody has to protect the piglets.
| I've got nobody but my horse,|
And my friend the cactus guy.
That's ok because I like them a lot,
That's ok I like being a robot, cowboy.
