Supposedly an adaptation of the Three Billy Goats Gruff fairy tale, it does have a couple of elements of that half-heartedly thrown in, but this is really a slightly revised version of The Sontaran Experiment. The author doesn't even try to hide what I can only assume can be considered plagiarism. Maybe he had persmission, I don't know. I also just don't know why. I guess the idea is that you could read this to a small child. I'm not sure what lesson they're supposed to take from the protagonists killing their foe and then laughing on the way home without a care in the world, but that seems to be the message in the original fairy tale as well. None of the billy goats ever asked "Do we have the right?"

A little strange that the gallifreyans are telling their kids so many stories about the sontarans, but hey ho.

This story is another fine one, it feels very fairy tale in it's morals (teamwork, brotherhood, courage, strength, and intellect all being useful, etc), but the story itself and the way it conveys those themes feels quite functional.

Like, it's a good story, dont' get me wrong, and the way they get those themes across is good, but that's just it, it's very much just 'good' as it were. It never does anything to make it rise higher than that
