Pet fish spend cash and expose Nintendo Switch owner's credit card during Pokemon live stream

The unlikely incident happened during an unusual experiment by a Japanese YouTuber, who wanted to see if his fish could complete a video game by themselves.

Footage shows them swimming across a grid mapped on to their bowl, with each square labelled with a command on the Switch's controller.

The fish had managed to complete a previous game in the series - and it only took north of 3,000 hours.

On this occasion, they had been playing for more than 1,100 hours when the game crashed, which is perhaps not a surprise, given the latest Pokemon games have been criticised for being prone to bugs.

Mutekimaru was away from his streaming setup when it happened - and the Switch continued to accept button commands from the fish.

Eventually, they managed to navigate to the console's store.

From there, the fish managed to add 500 yen (£3.10) to Mutekimaru's account using the credit card that was stored on his Switch - and expose the card details to everyone watching.

The fish also triggered a download from the store, had PayPal send their owner a confirmation email and changed their account name.

Nintendo seemed to take a sympathetic view of the situation, as Mutekimaru said the company granted a refund.

Sky News has contacted Nintendo for comment.
