The minisodes do what they need too

For an episode penned by children (to an extent at least), this is perfectly good. 'You went a bit ood- I mean you went a bit odd' is just a repetition of similar odd/ood jokes that have been made before, but that doesn't make it not funny.

This was really cute.  I'm not sure to what degree the children were really involved in writing the story, but it certainly has the spirit of something cool for a school to see come to life from their own mind.  It's not great but it's good enough for something meant to just be a little whimsical and get kids interesting in writing and storytelling.  It's very hard to object to that.

Apparently written by children, but you have to think that Moffat almost certainly touched up the script himself. Its serviceable as mini episode, but its main purpose is to give the competition winners, and those cheering them on, something to feel warm about. This is absolutely the sort of thing the production team should be engaging with.
