By request from my sister - here are some pictures of Fat Cat. Fat Cat (Frederick Alphonso Tubsy Cat) was the character on TV children's shows here in Perth when we were growing up.
We used to say goodnight to Fat Cat on TV when we were kids, because when Fat Cat was on then you knew it was time for bed.
Poor Fat Cat was questioned over the years about his gender identity; his obesity and his muteness - but to the kids who loved Fat Cat none of these things were an issue. Despite his show being cancelled, he is still a much loved Perth icon and mascot for Telethon to raise money for kid's illness and research. (See also Reg Whiteman Tribute.)
