Danny Kitchen just wanted to kill some zombies.

The 5-year-old asked his parents for the password to the family iPad to download a free game, only to accidentally rack up more than $2,500 in add-on purchases on his mother’s credit card.

Danny downloaded Zombies vs. Ninjas, a free game, from Apple’s App Store. His parents, who gave permission to play to game, left their son with the iPad while they tended to guests in their U.K home. Little did they know, young Danny ordered additional “darts” and “bombs” to battle the zombies, weapons that can cost up to $99.99.

His mother, Sharon, remained unaware of the purchases until she received 19 iTunes emails the following morning. Thinking it was a multiple send of one receipt, she ignored the message until her credit card company called her about the suspicious activity.

“I still find it incredible that he managed to do it,” Sharon tells Mashable. “He only had the iPad for ten to 15 minutes, so he could’ve only done the deed within this amount of time. He thought he wasn’t doing anything wrong.”

“He was reprimanded and told off, but he was crying,” Sharon explains. “He realized there were going to be consequences and I said, ‘You better run and hide,’ and he says, ‘But mommy, where shall I hide?’ I felt so sorry for him and couldn’t be mad.”
