Ivor Operatski

Mr. Ivor Operatski is a famous musician and director who appears in The Show Must Go On, and an episode of Series 2 called 'The Proposal.' He appears at first as an authoritative and short-tempered perfectionist who has little patience for mouselings, but Angelina helped him to show a warmer side to his angry personality, even going so far as to dress up as Father Christmas to get Henry to focus on his performance and atone for his shouting at him.

In 'The Proposal,' Angelina mistakenly thinks that he intends to marry Miss Lilly. Owing to his gruff exterior, she deliberately tries to sabotage their meetings, only to discover that he had intended to build a new theatre and wanted to ask Miss Lilly if the mouselings could perform at its opening ceremony!

Mrs. Hodgepodge is a great fan of his works.
