Very long, strange animated video, somewhat morbid, had kitten like animals?

I was in a bar a while ago and they were playing music and the video's to the songs were up on a big tv. They started playing a lot of techno and dubstep and a video came on the screen that was pretty long, multiple songs played through it so I don't know if it was a music video or just something they put on separately. It depicted a cartoon-like movie of two odd looking white kitten animals who were travelling on a boat with some sort of pig-like animal and they ate part of the pig. Next I saw that they were riding the pig through the dessert and beating it on the head until it dropped dead so they started walking. They came to a village and one of the kittens had its arm cut off so someone sewed it back on for him. Next they came to a big house with a creepy guy who had a bird or bat on a string flying in circles and then he lit it on fire so that it was a ball of fire flying in circles. He also had what seemed to be a ginger-bread house and he poured chocolate all over the roof. Next I saw that they were in what appeared to be a swimming pool or big tank of a milky looking substance and the kittens crawled out being chased by the weird man, one of them pulls the top of his head off and we see that he's a robot. They then take a pair of large scissors and cut the mans arms and legs off and he falls back into the tank. The next thing I noticed is that they are walking through the desert again and the sands start to fall away beneath their feat. It is the sands of time and they fall into a huge clock which is controlled by a huge guy that looks like gandalf the white, I'm guessing he's father time? He cranks time forward and back so that things grow very old and then very young again. The last thing I saw was the credits to the video which were all in chinese or japanese symbols so I wasn't able to identify the video. It was morbid in multiple ways but very intriguing at the same time. Any idea what it is?
