This is amazing! I've never seen singing eggs... and then they even get criminal! Great idea, great singing, great design of the eggs. I like the style of the main character. Fits perfectly. And the Master Egguru couldn't be anything then great.
Sometimes, the animation was a bit sticky, maybe try a bit more frames per second. Also, the change of aspect ratio confused me a bit. Still, a great film and maybe my faourite easter film right now!
