Schoolgirl smashes the world record as she lets 25 snails slide across her face
Her previous personal best was just nine.
The rules state that competitors have just one minute to put the snails on their face before tipping their head forward for 10 seconds.
Tiana, of Alvanley, Cheshire, said: "I am not squeamish. It is relaxing but it feels a bit cold. They are quite smelly and you can see their big long eyes facing you. I think my friends at school will say 'urgh'."
