Looking to create a unique and irregular animation, similar to the pattern of a waterdrop falling:
Drip
nothing
Drip
Drip
Drip
nothing
nothing
Is there a method to achieve this effect or loop an extended animation sequence of dripping?

Have you thought about developing a custom component to handle animations?
If you're utilizing the animation component, you can specify an event name to initiate the animation:
<a-sphere id="driplet" animation="...; startEvents: drip">
In this scenario, if you want to sequence the animations as play, wait, play, play, wait, you can achieve this by using a set interval to either emit the drip event or wait.
AFRAME.registerComponent("foo", {
init: function() {
// define the animation queue
const animationQueue = ["drip", "", "drip", "drip", ""]
// get the duration of the animations interval
var interval = this.el.getAttribute("animation").dur
// keep track of the current position in the queue
var animationIdx = 0;
// set up the event cycle
var intervalIdx = setInterval(e => {
// emit the event from the queue
this.el.emit(animationQueue[animationIdx])
// move to the next item in the queue
if (animationIdx < animationQueue.length - 1)
animationIdx++;
else
animationIdx = 0;
}, interval);
}
})

When it comes to implementing "tracked" animation techniques, one of the easiest methods I've discovered is through this reliable repository
https://github.com/protyze/aframe-alongpath-component
Arrange your water droplets along a path and animate them using specified x, y, z coordinates. Transform my x, y, z positions into a vertical orientation for the horse. This appears to be a straightforward approach unless you're aiming for something more intricate.
