Allicia Botti is a world-famous Italian opera singer.
When she first visited the Island of Sodor, Thomas was chosen to take her to the theatre, but after Allicia Botti discovered a mouse in Clarabel and screamed so loudly that all the windows in Brendam were shattered, Percy was chosen to take her to the concert. She frequently appears in concerts at the Town Square.
Allicia Botti usually wears a cream coloured dress-coat, with black fur trim, over a blue dress, with a black hat and pearl necklace.
