Nothing can stop the poop snails!

On the Japanese island of Hahajima, birds eat little snails. The snails then go through the bird's guts and get pooped out . . . and they often survive the trip!

This gives me hope in case a giant bird ever swallows me and then poops me out.

Wait— why am I hoping a giant bird will poop me out?
