Anyone that enjoys the way sour candy makes your mouth pucker also knows the burning sensation they can cause.

Lachlan Canuk, a 7-year-old from Australia, learned that the hard way when he began to feel his tongue burn after eating the super-sour candy Warheads.

The young man's mother was horrified by what she saw: a hole burned into her son's tongue.

The possibility of this happening isn’t a surprise, though.

The company uses the entire back of the candy's packaging to warn of side effects: "Eating multiple pieces within a short time period may cause a temporary irritation to sensitive tongues and mouths."

According to Internet reports, this isn't the first case of children being harmed by the popular sour treat.

Lachlan’s family hasn’t yet said if they’ll pursue legal action.
