Penguins!
I should have known that you, Wonchop, would submit something on Lock Day. This is among the most impressive things you have ever made! While I could tell what would happen at the end, what matters is that what happens on the way is so impressive! I honestly think this is the first time I have ever seen a Ninja Cthluthu. The CGI penguins are also awesome and may be the best part of the entire movie. The regular animation (and the people who helped) was by itself great as always and happy belated Lock Day!
