The show first started on 13 June 2004 and ended on 8 April 2005. The protagonist is Roly Mo, voiced by Wayne Forester, a green and purple striped mole who lives underground and likes to read books. Roly Mo was a regular storyteller character in the better known Fimbles show, and The Roly Mo Show draws heavily on this. The show is noted for its particularly gentle and pleasant characters and plots.
It starts with Little Bo and Bessie Bird (Norman) visiting Roly Mo after school. She hangs up her rucksack and hat and goes down the slide into the main part of Roly's house.
One of the characters has a problem; this is the main plot element throughout the episode.
Someone reads a story from Roly Mo's library, preceded by the "Inside a book" song. Most of the time this is Roly, although sometimes this is Little Bo, Rockit, Yugo and Migo or a combination. The story is related to the problem and often gives an idea for its solution.
Little Bo looks in her 'Busy Book', starting the segment of an animated Fimble solving an educational puzzle.
The problem is solved, often with a song.
The show closes with voice-overs during the credits, and is often humorous or providing further closure.
Little Bo - a younger and highly intelligent mole. Little Bo has pink and purple stripes, and is Roly's niece. Little Bo is voiced by Tamsin Heatley.
Yugo and Migo - Yugo and Migo are Snoots; orange and yellow fox-like characters. Yugo is striped and Migo is spotted. They are slightly dim and manic, and probably created for the amusement of younger viewers.
