Information for The Princess and the Pea at Unicorn Theatre, Inner London (Kids show). Traditional story of a princess whose royal background is put to the test by a pea placed under several mattresses. Will she notice the tiny lump in the bed as a real princess should, or is she an impostor? Breathtaking acrobatics, clowning, and fairy-tale adventure combine in this funny and playful remix of Hans Christian Andersen's classic story. A Unicorn co-production with New Vic Theatre and leading contemporary circus company Upswing.
