A gran was forced to write an apology note to her granddaughter's teacher when the youngster used permanent marker to draw on bushy eyebrows.
Louisa Jackson, 59, arranged to take her six-year-old granddaughter Phoebe to school as a favour to her daughter Amy.
The gran-of-four asked Phoebe to brush her teeth before the pair left the house for school.
But when the youngster came down the stairs, she was sporting a pair of giant Sharpie eyebrows 'like Groucho Marx'.
Louisa spent 10 minutes trying to scrub them off, eventually removing the worst of the ink with baby oil and cotton wool.
But Phoebe still had a 'grubby' smudge on her face, so Louisa was forced to write a note to her school explaining what had happened.
She has now vowed to keep permanent markers hidden away in future - after Phoebe also painted herself red in a bid to look like the crab from The Little Mermaid.
Louisa, from Bexley in Kent, said: "When I looked at her I just thought she looked just like Groucho Marx.
"When I was small I used to go to the Saturday morning pictures and they used to show the Marx Brothers films.
"I thought it was Amy's mascara to start with, which is easy to take off. So I just got baby wipes and wiped it and nothing happened.
"I said to Phoebe 'why have you got Mummy's make up on?' and she said 'it's not, it's pen'.
"I realised it was permanent marker when it wouldn't budge.
"I was scrubbing them for ten minutes, then poured baby oil on some cotton wool and that's when it started to come off, but it was still pretty dark.
"She just loves make-up and obviously she just decided that she wanted eyebrows that day."
After racing against the clock to get the pen off and Phoebe to class in time, Louisa also quickly penned an explanatory note for her teacher and handed it in.
Louisa said: "Phoebe had to go to school with a smudge on her face so I put a note in her book bag.
"I wrote 'I'm sorry if Phoebe's face looks a bit grubby but she drew eyebrows on with a permanent marker and I've done my best to take it off.
"We'll definitely make sure permanent markers are out of her reach in future.
"As she's getting bigger she can reach more things and you don't realise what she can reach until something like this happens."
Three years ago, Phoebe covered herself in red felt tip pen in a bid to transform herself into Sebastian from The Little Mermaid.
Louisa said: "When she was three she coloured herself in red after watching The Little Mermaid.
"She said 'look I'm a crab', that came off in the bath as it was ordinary children's felt tip pen."
Sharing her permanent marker predicament on Facebook, Louisa wrote: "Grandma fail!
"My only mission was [to] have her overnight, get her to school on time Monday morning.
"Mission complete but I have yet to tell mummy I sent her up to brush her teeth and she came down [with] permanent marker eyebrows.
"Got most of it off with wipes and baby oil but had to put a note for the teacher in her book bag as she still looks a little bit like Groucho Marx."
Social media users were tickled by the picture and joked that they saw eyebrows like this on women on night's out.
One said: "To be fair I've seen actual adults draw their eyebrows on like that and go out on a Saturday night."
Another wrote: "Better than some of the brows I see today."
