An Australian teenager blamed the influence of marijuana for his decision to steal two crocodiles and a monkey, local media reported Wednesday.

Benjamin Glen Watts, 19, pleaded guilty in court Tuesday to twice breaking into a wildlife park on the outskirts of the tropical city of Darwin last July, Australian Broadcasting Corp. radio reported on its Web site.

Watts said he planned to sell the stolen baby crocodiles and the marmoset but had been unable to find buyers, ABC reported.

Crocodylus Park spokesman Grahame Webb said Wednesday the animals were returned unharmed.

Watts' lawyer told the court his client admitted it was a "dumb stoner" thing to do and had written to Crocodylus Park to apologize.

Magistrate Greg Cavanagh sentenced Watts to a three-month suspended jail sentence. Watts has been counseled for his marijuana use since the thefts.

A court official was not immediately available for comment.
