Changes

It's autumn term for Humphrey the Hamster, Og the Frog and the humans that use Room 26 of Longfellow School. In the run-up to Halloween things get a bit spooky and mysterious. Where has the usual teacher gone? And what is her replacement up to - he's certainly not teaching anyone anything with his fun japes. In this episode in the series Humphrey must help the clumsy child, the over-the-top flat-out lying child, and most of all work out why the teacher disappeared all of a sudden, leaving the classroom halfway through reading out a Sherlock Holmes adventure.

For once, the way Humphrey helps the children out are obvious and too simplistic. That's true too of the main plot, where our hero is deluded into thinking the missing teacher has left the lovely class and become a ballet dancer. We can too easily figure out the truth. And whereas before the plot was an all-encompassing whole, here the fact the intrigue is part-inspired by a mystery story doesn't hang together, or get used well enough.
