There were a few raised eyebrows on the streets of central London today after a 3 tonne polar bear went on the rampage.
It was actually a puppet - operated by fifteen puppeteers.
But thousands came to see it nonetheless.
It was part of an international day of action against drilling in the Arctic.
Hundreds of people in polar-themed costumes are expected to join an Arctic-inspired street parade which will stream through central London as part of a global day of action to protect the pristine region at the top of the world.
The crowd of white-clad Arctic defenders, including people wearing polar bear costumes will be led by the world's largest polar bear puppet - a three-tonne marionette the size of a double decker bus, named Aurora. The giant bear will be operated by a team of 15 puppeteers.
The family-friendly parade will walk past Westminster heading for oil giant Shell's HQ on the Southbank, where a creative and peaceful demonstration against the company's Arctic drilling plans will take place.
A three-tonne polar bear puppet, the size of a double decker bus, is heading to London as part of a worldwide campaign to raise awareness of the Arctic and changes to its environment.
The puppet will be operated from the inside by a team of 15 puppeteers as it makes its way along a route including the Houses of Parliament and Westminster Bridge on 15 September.
The giant bear, which is made of replica and reclaimed ship parts as well as recycled materials, will be carrying in her fur the names of over 3 and half million people who have joined a global movement to protect the Arctic.
