This is quite a funny animated movie using Open Source software Blender. The quality is certainly as good as Pixar, although the storyline could use some better editing. The humour is reminiscent of Bugs Bunny/Road Runner vs Wiley Coyote and I would rate this as PG. The graphics are really very high quality and that makes the slap-stick/retribution style humour more intense.

The children have watched it a couple of times already and want to watch it again.
