Thanks. I believe there are many crazy toads in here. Toads live in one area and breed in others. Every year, in a gregarious way, they all migrate in the same direction. When we build new roads across, they get run over en masse.
Except... some go the other way, or find the tunnels that environmentalists have dug for them under the roads. Because they venture in unconventional directions, these crazy toads are inventing ways forward and saving the species.
