This is your go-to when you need animations that make people smile instead of just moving pixels around. It leans hard into Disney's animation principles but cranks everything up: 25-40% squash and stretch, bouncy overshoots with cubic-bezier curves that go negative, and secondary actions everywhere. You get specific timing recommendations (400-600ms bounces, 150-250ms pops) and ready-to-use keyframes for wiggles and boings. Best for games, kids' apps, social reactions, and anywhere you want cartoon physics over corporate polish. The timing tables and easing functions alone save you an hour of tweaking values until something feels right.
