 Cane Toads is a documentary detailing the spread of Hawaiian sugar-cane toads (toads which live in the cane fields) through Queensland and then into the rest of Australia following a mis-informed attempt to introduce them to counter pests. Turns out they wouldn t eat the  cane grubs  but they would multiply like no one s business... and they have no natural enemies in Australia at all, partly due to their poisonous skin.
