Animate the frog as one seamless happy loop; for frame 0, change the supplied held wide-laugh pose into a small shallow closed smile by shrinking and shallowing the mouth, lifting the lower edge, hiding the tongue, and moving the closed crescent eyes slightly downward. From that frame-0 pose, the mouth cycles from a small shallow smile into a broad open grin: the opening widens and deepens, the lower edge drops, the white upper smile band stretches across the top, and the pink tongue is revealed at the lower center; hold this wide-open laugh through the middle of the loop, then shrink the mouth back into the small closed smile near the end, hiding the tongue. The closed crescent eyes keep their shape but drift slightly upward as the mouth opens, remain raised during the open laugh, then glide downward as the mouth closes. The torso and belly bob vertically in two complete up-down cycles while the head and limbs stay essentially fixed: the body rises first as the mouth opens, settles back down while the broad open grin is held, rises a second time during the held laugh, then returns down as the smile closes. Use smooth ease-in/ease-out timing with no hard cuts except the mouth shape morphing through progressively larger smile states.
