All the emotion of Toy Story or Wall-E, but in just a few minutes.
Partly Cloudy (2009)
Clouds make adorable baby animals and storks carry them to their new homes in Partly Cloudy, except there's one cloud who doesn't quite get it. Instead of puppies and kittens, he's making crocodiles and porcupines, much to the horror of his poor stork. As with a lot of Pixar, the animation is cute and the story is both funny and heartwarming – without being overly soppy.

Day & Night (2010)
Day & Night is made brilliant by its outstanding use of animation and sound, but it also carries a really strong message of leaving your comfort zone and embracing new ideas – which is put across perfectly through the use of an extract from a speech by Dr Wayne Dyer called "Fear of the Unknown". This is up there with Pixar's very best shorts, and it may even be the best of all. If you've not seen it, it's an absolute must-watch, and if you have, then watch it again.
