Nature

Originally introduced to the country in order to eat up beetles that were destroying the sugar harvest, Cane toads are now bounding across Australia at an alarming rate.

The trouble is, they're toxic creatures, even at the tadpole stage, so anything that feeds on them dies.

Originally from South America, these toads are smart, very smart. They form toad pyramids to get at food, they tap on the outside of beehives to get the bees to come out and be eaten, in fact very little stops these boyos. You can't help but grudgingly admire them.

The big worry is that they're now heading for the Kakadu National Park, and once they're in there there'll be trouble.
