This came on BBC1 on Christmas Day, and like Wallace and Gromit before it, I recorded it so it could be watched later. I've finally got around to watching it, and I was pleasantly surprised.
With a solid voice cast voicing the animals, the rhyming dialogue is sweet and never annoying.
The story of the mouse, as told by a mother squirrel to her two babies is episodic but suitably so. The jokes were funny and it was even somewhat dark in places where it needed to be.
The animation is probably not as polished as Lost and Found(2008) but has it's own caricatured, simplistic charm and is aesthetically faithful to the book(haven't read it, but have seen the cover).
Overall, an entertaining and amusing short about deception and survival done in a colourful and light way. I enjoyed it along with The First Snow of Winter, also based on a picture book, that has a similar tone, also featuring a 'big, bad' wolf. Good for young kids and the young at heart.
