Wacaday was introduced when Roland Rat, the puppet host of TV-am's previous weekday morning slot during school holidays, transferred to the BBC.
[2][3] With only a week until October half term was due to start, it was decided to produce a spin-off of the existing and successful Saturday morning programme, Wide Awake Club.
Other regular features included a narrated story about the adventures of Magic, Timmy's cockatiel, various phone-in quizzes (typically at the end of the programme) where a selected viewer would compete in some gunge-related competition, and a short five-minute cartoon, such as Transformers, Galaxy High School, Batfink, Challenge of the GoBots or Dick Tracy.
Although some minor items appeared and were retired over the years, the overall structure of the series remained the same throughout the show's life.
The self-proclaimed 'show your telly was made for' eventually became even more successful than Wide Awake Club and is the programme for which Mallett is probably best remembered.
The 2007 debut release by British trio Scouting For Girls contains a tribute to Michaela Strachan and Wacaday in a hidden track 11.
