Here is the animation! After Effects is a very helpful motion graphics app. It can also be used for animation, but I would more so recommend Adobe Animate for animating stuff. Anywho, I made the head bobble by creating keyframes where the head would rotate left and right. But without Easy Ease, it doesn't look very good. So, Right Click on Keyframe > Keyframe Assistant > Easy Ease. After Effects tweens for you, but uses Classic Ease, which makes it look weird. Luckily, we can choose from different Eases! Easy Ease, Ease In, and Ease Out. I also keyframed the body so it looked like it was dancing. I made the eyes bounce by using the Scale keyframe, and then I keyframed it getting slightly bigger after the pop in. I AGAIN used Easy Ease to make it look like it just bounces in.
