The movie I’m trying to find is one I watched over six years ago. The movie itself may be older.

It was a 2d animated cartoon. I don’t think there was any talking during it. It may have been a very short movie, like 15 minutes.

What I remember is that the main character went to a beach. He had these 2d shapes, and he was able to blow them up like balloons into other people. I think he made a man and a woman. He eventually popped them and I think they reverted back to their orignal shape. Then the main character stepped on a needle I think and he turned into a triangle.

This movie is so hard to find. I’m not sure if it even counts as a movie. But if you have any clue, please help! Thanks
