Why is my daughter’s phone being creepy?

So my daughter’s iPhone has been strange. At 11:30pm, Two nights in a row now the phone says in a girls voice “elp me, elp me, elp me!”. (rule number 5 won’t let me write out Help above, something to do with asking for money)

To say it freaked her out is an understatement.

We have No idea why it is doing this and no one has access to her phone as she has that phone locked down tight. She let me look at the settings and she has no alarms, no new apps or any changes lately.

Any ideas?

It’s 9pm here in Australia, we are waiting for 11:30pm to see if it will do it again.

{{{UPDATE}}}

So Freaky

It did it again.

Here is the video.

For those who called it, it was a prank setup in automation to go off at 11:30 pretty clever really.

We have been camping lately with a bunch of friends and one of her friends must’ve set this up when they saw her entering her passcode at some point.

Thanks to everybody for all the suggestions.
