Halloween may be a predominantly American thing, but city residents can get the spooky vibe of the festival in a jungle on Wednesday.

The city-based green organisation Tarumitra will organise a Halloween party and the venue will be decorated like a forest, with owls, bats and spiders. There will also be hanging pumpkins cut into scary shapes with candles inside — the Halloween staple jack-o'-lantern.

Everything will be made out of recycled paper.

The party will start around 5pm and end around 7pm. The Tarumitra folks have requested people to turn up in red or black dress in keeping with the Halloween theme. Tarumitra co-ordinator Devopriya said participants would also be given props such as witches’ hats, brooms, masks and horns.

“We will also be painting the face of two to three children in white and their job will be to scare people. They will suddenly appear in front of the participants. We are not forcing participants to dress up like ghosts or any other scary characters. It is their own wish,” said Devopriya.

The refreshments that will be given to people would also have spooky feeling, she said.

“We will give mixed fruit juice but its colour would be blood red, and there will be cookies in the shape of eyes. Everything will be nature-friendly as we will be using disposable plates made of tree leaves. We will be using steel glasses to serve juices and not plastic cups,” she added.

The idea, she said, is to make people realise that the thing the should be most scared of is global warming and its threat to the very existence of humankind.

“We are responsible for the darkness that has engulfed our nature. The global warming has been caused due to people putting extreme pressure on nature and its objects. This will also be taught to people in one session,” she said.
