Hah, that turtle... this could be the start of a series. :P Have you ever watched the old Knox claymations? Might be some inspiration, though they often take a turn for the violent, not as inoffensively creative as this. I liked the pace with the faces, though maybe slow down a bit just after they've shifted expression? The shifts were really smooth otherwise, and at the start it kinda expands out of the ground too, that's a neat effect. Looking forward to the next one!
