Fantastic Voyage

A similar concept was used in the 1987 movie Innerspace.

A song by funk and R&B band Lakeside, released on their 1980 album Fantastic Voyage. A delightful alliteration inviting listeners to "slide, slide, slippity slide" and to "come along on a fantastic voyage," combined with an infectious hook and ultrafunky bassline made it a hit. This second single became Lakeside's biggest pop hit and an R&B chart-topper. It was more recently revived in 1995 by rap star Coolio.

This Atari 2600 game is based on the movie of the same name. You have to pilot your tiny ship inside of a human body to battle infection and fight disease. My copy of this game no longer works, (but I remember it being pretty difficult)

This game is valued at around $8 USD. Games with boxes and manuals are worth more.
