A bushtucker trial complete with edible grasshoppers and worms could be your treat this Halloween.

Staff at Hunstanton Sea Life Sanctuary are daring families to try their new Rainforest Ranger themed trick or treat yucky dip.

Those brave enough to take part in the trick or treat activity will be presented with two boxes, one with chocolate treats and one concealing edible insects, including grasshoppers and several different types of worm.

Participants will then be invited to eat whichever delicacy they pull from the box of their choice.

Aquarist Natalie Emmerson said: 'In many areas of the world eating insects is actually quite common, including in the Amazon Rainforest, the tropical forest which our own Rainforest Ranger experience is based on.

'In the UK the idea of eating insects tends to freak a lot of people out though, so will be quite a challenge – we think a lot of dads will be dared to try it by their kids.'

Participants will be encouraged to make a 50p donation towards Merlin's Magic Wand, a charity founded by Hunstanton Sea Life Sanctuary's parent company Merlin Entertainments, which arranges days out for seriously ill, disabled and disadvantaged children.

Ms Emmerson added: 'We thought we'd give guests the opportunity to take part in a really unusual trick or treat activity this Halloween and raise money for Merlin's Magic Wand at the same time.

'Of course, it's not safe to go out and start gobbling up any old insect from the wild, some are very poisonous.

'The insects in our yucky dip have been ordered specially and selected for human consumption, so will be perfectly fine to eat – it's just a case of mind over matter swallowing them down – they're actually supposed to be pretty tasty, and quite good for you as they are high in protein.'

Hunstanton Sea Life Sanctuary's yucky dip trick or treat is an optional activity located outside the sanctuary's Rainforest Ranger area, which houses creatures hailing from the Amazon Rainforest such as leafcutter ants, lizards and snakes.

It will take place on Saturday, October 28 and Sunday, October 29, between 11am and 12pm and 2pm and 3pm.
