Series for pre-school children. Little Bo visits her uncle, Roly Mo, in Fimble Valley every day and there's always something exciting to do during a visit, especially when Yugo and Migo are close at hand. Roly, Little Bo, Yugo and Migo have their own best things, but there are some things that they can share too. Homework should be as easy as 1-2-3, but Little Bo finds that the number three isn't always where it should be.
