Central Sydney has been invaded by giant neon snails as part of the city's Art and About festival.
But local gardens have nothing to fear from the 24 mammoth molluscs, even though each weights more than 100 kilograms and is more than three metres high.
The snails are made from recycled plastic and are designed to encourage people to see Sydney in a different light and to encourage the creation of more sustainable environments.
Snailovation, as the collection is known, has been spread around various CBD locations for the next month, including Customs House, Martin Place, the Pitt Street Mall and Hyde Park.
The creatures were created by the art collective Cracking Art Group, a partnership of six artists from Italy, Belgium and France formed 20 years ago.
Snailovation first appeared three years ago in the United States at the Art Basel show at Miami Beach.
Cracking Art Group have previously created colourful plastic animals including turtles, crocodiles, dolphins, penguins, meerkats and seagulls.
The Art and About festival runs for the next month, with more than 50 exhibitions, events and workshops on the agenda.
