I know, I promised an AMV, but this was hard enough despite all the homework and stuff. Enjoy. Took like and hour or two, maybe more. If you don't get it, read the books.
Relation to Song:
"I left my best friends" - Going into the tunnels and not returning.
"Or did they just leave me?" - The other cats went to the mountains and left him behind.
"Lost and never found" - He never escaped the tunnels.
"Check for something I couldn't find at home" - Trying to become a sharpclaw.
"Run away before you drown" - Don't drown in the tunnels!
"The streets will be condemned!" - The tunnels are blocked from the other cats.
"Fallen leaves" - His name.
"On the ground" - The mission was underground.
"Got no job, could you spare a dime?" - He helped Jayfeather, but in the end, was clueless.
"Fallen leaves! Fallen leaves! - Fallen leaves!" The chanting of the live cats outside the tunnels.
"This could be my one last time!" - He fears he might be killed by rainwater.
