The 25-30 centimetre crocodiles are still at the pool in a turtle tank waiting to be picked up by local snake and reptile handler Gavin Lawrence.

He said what started as a harmless prank ended up killing one of the baby crocodiles.

"It's annoying they've dumped them in the pool," he said.

"The chlorine is no good for them and at the end of the day it's sort of reckless."

Mrs Rodriquez said she suspected the baby crocodile succumbed to the heat after it was found after closing time outside of the pool.
