Motion edit prompt

Use the provided SVG as the frame-0 starting state with no edits. Start with a quick squash-and-stretch: the emoji head widens and flattens while the existing eyes and straight mouth move downward together and compress horizontally. At the bottom of the squash, instantly hide the flat mouth and first slanted eyes and instantly reveal a clenched expression: show the rounded horizontal gritted-teeth capsule with vertical divider strokes, and show the sharp inward-pointing V-like eyebrow strokes above it. Launch this new face group sharply upward toward the top of the head with one leftward move first, then rebound it side-to-side in a tight angry shake for two full left-right cycles, moving right, left, right, and left while keeping the teeth mouth locked beneath the brows. Hold the head slightly squashed during the shake, then let it stretch back to the size and round shape it has in the provided SVG as the clenched face recenters and settles downward about one-and-a-quarter mouth-capsule heights from its shake height, ending with the teeth capsule across the middle of the head and the brows fully inside the head outline.
