Do you want to know why your spaghetti was squirmy and squishy? And why it had a nasty bitter taste? Because it was worms! 

This is just one of the many tricks played by Mr and Mrs Twit in Roald Dahl's highly acclaimed children's book The Twits, which will be performed at Beaumaris Castle on Saturday 21st July 2012.

The show promises to be slimily, stickily and revoltingly funny, which will have children of all ages captivated and enjoying every minute as it tells the story of Mr and Mrs Twit who loathe one another and spend their lives playing nasty tricks on each other. From slimy frogs in the bed, to a glass eye in a beer, the Twits eventually get bored of playing tricks and decide to open a circus, capturing a family of monkeys and cruelly training them to perform in the ring. Only with the audience's help, though, will the Twits meet a sticky end and will the monkeys finally be set free.

Roald Dahl is perhaps the most popular children's author in the world. This adaptation by David Wood, the leading writer/director for children in the country and who directed the West End production of The BFG, will be performed by IIlyria, a top-quality UK open air touring theatre company who will bring The Twits to life amongst the wonderful setting of Beaumaris Castle.  

Karen Harper from the White Lion Hotel, one of the organisers, said:  "Children just love Roald Dahl, and The Twits is one of his best. Although Mr and Mrs Twit are everything adults despise, being smelly and truly horrible, children adore it, especially as the tale evolves and they eventually get their comeuppance. This really will be a performance not to miss and a great way to start the school holidays! 

"We are restricted on ticket numbers though, so I would urge parents to get their tickets soon!"

Tickets are only £12 for adults, £7 for children or a family ticket (2+2) for £31 and are available from selected outlets in Beaumaris or from www.beaumariscastleevents.com or www.illyria.uk.com

The performance starts at 6.00pm, but Beaumaris Castle gates will open at 4.30pm to allow families to enjoy a picnic in the grounds. Snacks and refreshments will also be available beforehand and during the interval.  

The Twits has been organised by six businesses in Beaumaris: White Lion Hotel, Red Boat Ice Cream Parlour, Puffin Holidays, Janet Bell Gallery, Cole & Co and Bishopsgate House Hotel, with all proceeds from the night going to Gwynedd Sands, the stillborn and neonatal death charity.
