Squash and stretch
The prompt “A 2D cartoon character, a small red rubber ball with stubby arms and big eyes, hops off a table edge, squashes flat on landing, stretches tall as it bounces back up, lands again and reacts with a wide-eyed surprised expression. Classic cartoon timing, flat colors, static camera.”
Tests the core principles of cartoon motion: anticipation, squash and stretch that keeps the volume, exaggerated timing and an expression change that reads at a glance.

Kling 4.0
KuaishouEvery principle asked for: a squash in anticipation, a stretched hop, a flat splat on landing, a tall rebound and a wide-eyed surprised face, all on a static camera.
Google Gemini Omni
GoogleTextbook cartoon timing: anticipation before the hop, a flat squash on landing, a stretched rebound with speed lines and a second squash before the surprised face. The camera pans down to follow the fall.
Seedance 2.5
ByteDanceFlat 2D with a stretched fall, a very flat squash and a rebound into a surprised face. The squash is held for two seconds, longer than cartoon timing would.
Google Veo 3.1
GoogleHops off the edge, splats into a flat puddle with impact lines, stretches tall on the rebound and ends with a round surprised mouth. The rebound leaves the top of the frame for a moment.
FLUX 3
Black Forest LabsFlat 2D with a stretched fall, a wide squash that holds about 1.5 seconds, a tall rebound and a mild surprised look at the end. The camera pans down to follow the fall.
Seedance 2.0
ByteDanceClean anticipation, stretch while falling, squash on landing and a surprised face at the end, but the ball is a glossy 3D model in a photographic room rather than flat 2D.
Grok Video
xAIStrong squash on landing, a tall stretch on the rebound and a clear surprised face at the end. On the rebound the ball passes in front of the table it was sitting behind a moment earlier.
MiniMax Hailuo 02
MiniMaxBig, readable squash and stretch, from a flat pancake to a tall cone, but the ball lands on the table and never hops off its edge. The clip is 6 seconds long.
Kling 3.0
KuaishouThe ball drops from a stone ledge rather than a table, flattens into a ring-shaped splat that holds for about 1.5 seconds, stretches tall and then spends two seconds with its back to the camera before the surprised face returns.
Vivix W1
VivixLively squash and stretch and a strong surprised face, but it is a 3D render in a photographic kitchen rather than flat 2D, and the framing jumps to a close-up mid-fall at about 2.2 seconds.
Wan 3.0
AlibabaClean flat 2D and a clear surprised face at the end, but the ball barely deforms: it stays almost round through the landings. The framing changes at about 1.7 and 2.2 seconds and pushes in at the end.
MiniMax H3
MiniMaxRendered as a 3D character rather than flat 2D, with the camera tilting down to follow the fall. The squash is good but the stretch thins the body into a stick, so volume is not kept.
Kling 3.0 Turbo
KuaishouSquash on landing and a tall stretch afterwards, but the ball is tiny in the first shot, the clip cuts to a closer framing at 3.2 seconds, and the stretch is held still for about 1.5 seconds.
Runway Gen-4.5
RunwayThe squash and the bounces read well, but the face and arms vanish for most of the clip: the ball is a plain red sphere from about 1 to 5 seconds and the face only returns at 6 seconds.
PixVerse v5.5
PixVerseThe ball lands on its feet like a walking egg, then lies face down on the floor for three seconds instead of squashing and rebounding. The camera follows the fall and the room layout changes as it does. The surprised face at the end reads well.
