“It’s my first pony convention. I collected them when I was younger but when I was 10 I stopped,” Swede Rebecca Lindahl, 21, told British local paper the Nottingham Post.
Lindahl attended the two-day event, called UK PonyCon 2012, together with a friend from Sweden.
Lindahl said she started collecting My Little Pony toys again this year because she “wanted a new hobby.”
“I had 20 ponies from my childhood and, after just a year of collecting, I have about 150 now,” she told the paper.
“I’ve spent a couple of hundred pounds in the last year, but it’s worth it. It’s my money to spend.”
“My friends think I’m crazy anyway and my family love it.”
At the convention, women in their twenties to forties talked about their love for toy ponies, reports the Nottingham Post.
Many were dressed in My Little Pony t-shirts or fancy-dress outfits. Some wore brightly coloured wigs.
The conference also included a series of specialist talks, screenings and an extensive display of tens of thousands of the collectable toys.
Dozens of male fans, who proudly call themselves Bronies, raved about the My Little Pony series at the convention.
My Little Pony was first launched in 1983 by toy maker Hasbro, and has been relaunched several times since, inspiring an animated feature-length film and three TV cartoon series.
