Action + Sound Design: [0-2s] Wide establishing shot of a sunny pond. The green frog sits on the muddy bank, eyes wide and curious, slowly reaching toward a large glowing pink pearl inside an open clam shell. Soft ambient pond sounds: gentle water lapping, distant birds, light wind through reeds. [2-3s] Close-up on the frog's face: pupils dilated, tongue slightly out, finger hovering just above the pearl. Tense silence with a faint magical shimmer from the pearl. [3-4s] The clam snaps shut on the frog's finger with a sharp CLACK. The frog's eyes bulge, mouth drops open in shock. Loud snap sound. [4-6s] The frog yanks its hand back and hops backward, clutching its throbbing swollen red finger. Pained "YOW!" vocalization, rapid heartbeat sound. [6-8s] The frog stumbles and accidentally kicks the clam shell, sending it spinning into the air. Whoosh sound, panicked breathing. [8-9s] The clam arcs through the air and lands squarely on the head of a grumpy brown beaver <<<Image3>>> sitting nearby. Dull thud, beaver's surprised grunt. [9-11s] The beaver slowly turns its head toward the frog, eyes narrowing, buck teeth gritted, the clam still balanced on its head. Low ominous rumble. [11-13s] The frog looks up, frozen in fear, then forces a nervous toothy smile with a visible sweat drop. Awkward gulp, nervous giggle. [13-14s] The frog's smile drops; it spins around and sprints away in panic. Fast scurrying footsteps, splashing mud. [14-16s] The beaver snarls and charges after the frog on all fours, kicking up dust from the muddy bank. Heavy charging footsteps, angry growl. [16-18s] The frog leaps into the air trying to escape; the beaver pivots and swings its broad flat tail like a baseball bat. Tail swoosh, frog's scream. [18-19s] The frog is struck mid-air and spins wildly out of control. Impact smack, whoosh. [19-21s] Wide tracking shot: the frog flies across the pond in a high arc, limbs flailing, heading toward a large tree trunk on the far bank. Wind rushing sound. [21-22s] The frog splats flat against the tree trunk with a wet SPLAT, then peels off and slides down into the mud. Squish, mud splatter. [22-23s] The frog sits dazed in the mud, stars circling its head, tongue lolling out. Dizzy sound effect, tweeting birds. [23-25s] The frog's eyes refocus and spot a small bright multicolored spiky caterpillar <<<Image1>>> crawling on a nearby leaf. Curious "hmm" sound, leaf rustle. [25-27s] The frog's tongue shoots out fast, wraps around the caterpillar, and snaps back into its mouth. Tongue snap, slurp. [27-28s] The frog chews once, eyes widen in pain, and spits the caterpillar out in a puff of dust and spikes. Crunch, "OW!", spitting sound. [28-30s] Extreme close-up on the frog's face: its lips swell to enormous, glossy bright red proportions. Comic rubber-stretch swelling sound with a pop, ending on a sad groan.
