An 11-year-old Kentucky boy suffered severe burns when his friend pranked him as part of the viral “Hot Water Challenge” — and now charges have been filed against the mother of the pal who allegedly dumped scalding water on him, authorities said.

Billy Oliver awoke around 2:30 a.m. Tuesday to boiling water being dumped on him during a sleepover at his friend’s house in Manchester, news station WYMT-TV reported.

“He went to sleep and woke with his friend throwing boiling water on him laughing while my child [fought] to get his clothes off,” his mother, Patricia Oliver, wrote in a Facebook post, according to the Kentucky Herald-Leader.

The boy was left with burns on his neck from the dangerous social media challenge, which involves people drinking or pouring boiling water on themselves or someone else.

Billy was brought to the hospital then transferred to Cincinnati Burn Center, where was treated for second- and third-degree burns, authorities said.

“On a zero-to-10 scale how bad it hurt, it was a 10,” Billy told WYMT.

The friend’s mom, Angela Guth, is accused of not seeking medical help for the child following the incident.

Guth, 42, turned herself in Friday afternoon on charges of criminal abuse and wanton endangerment, authorities said.
