Answer:
Beetles began devouring Sugar Cane field in Queensland, Australia in 1930, so Farmers got desperate.Tales quickly spread of a toad that loved nothing more than to dine on cane beetles.The thinking went that a few hundred cane toads which can grow as large as dinner plates and weigh up to 4.5 pounds (2 kilograms) would gobble up all the cane beetles so that farmers could get back to farming.
In 1935, two suitcases of South American cane toads made the journey from Puerto Rico where a similar scheme was successful to Hawaii and then on to Australia. Rather than hang out in the cane fields though, those original 102 toads set out across the continent and have mushroomed in number to more than 1.5 billion.
Today, toads have conquered more than 386,000 square miles (1 million square kilometers) of Australia.
