Strong rule: style --- 3D Pixar ---. The triangle has its back to the camera, waiting for the train to arrive. The train arrives, slams on the brakes, the doors open. The triangle, as it is first, is pushed by a crowd of people behind him and enters the carriage. The triangle, at the last moment, is the last to grab the train door and manages to enter the compartment
Character appearance reference (MUST match exactly):
- Triangle: A young male anthropomorphic green triangle character with a solid green skin tone. He has a large, equilateral triangle body that serves as his face and torso. His face features large, half-lidded white eyes with black pupils, thick expressive black eyebrows, and a small, thoughtful smirk. He has thin, lanky green arms and legs. He is wearing a brown backpack with straps over his upper corners. His pose is contemplative, with one hand resting on his chin and the other arm bent as if checking a watch on his wrist. He has a skeptical and slightly impatient expression.
