These are stories about Invisalingua and Tiny Man. As Felicia Day describes Invisalingua and Tiny Man during her Geek & Sundry "The Flog" episode "Felicia Day Drives a MotherF% BULLDOZER-THING!"
"I'd love to be able to speak all languages and be invisible...my name would be something inspired by those powers. Um...let's say..."Invisalingua"!...As for a sidekick, I'd like a tiny man named "Tiny Man", because he could get in and out of cracks I couldn't fit in. He would have emotional problems because he's too tiny, but later meet, and marry, a fairy. The story pretty much writes itself."
