Nothing much to write home about here but as a short story for kids its got a certain level of charm. It absolutely feels like the sort of story Rose would make an offhanded comment about happening offscreen in Boom Town or School Reunion which is really enjoyable to read as one of these shorts.

The couple of times 10 says 'best in the known universe, well, half the unknown universe too' is also just a fun little phrase that I love from the doc.

Overall it's lighthearted fluff and not much more, but that fluff is fun fluff.
