Why is a woman riding a giant snail through Norwich city centre?

This afternoon a woman is riding a giant snail through Norwich...and it's all to promote a circus festival.

The International Festival of Circus and Street Arts kicks off in Great Yarmouth this weekend.

Most of the action takes place in St George's Park but there'll be circus performers all around town.

It's not just giant snails punters can expect: dancing, juggling, puppetry, circus, storytelling, wire walking, and music.

You can check out the festival's programme here.
