Hopping of thirst.

A huge kangaroo has had a stressful battle with a watering can after getting his poor little head stuck at Coffin Bay in South Australia.

A professional "kangaroo wrangler", Rob Smith, told ABC Open dry conditions meant all native animals have been struggling to find water.

"This guy obviously found a watering can with a bit of water in the bottom of it and he's decided to poke his head in there," he said.

"It all went a bit pear shaped for him."

Smith and one of his mates tied a rope to the can and tried to help it off the roo's head.
