Draw animation and motion path menu

So, i made this:

Not for any particular reason, i had the idea and was curious if i could. It came out fairly well (could use some polish), but it definitely functions as intended.

Im curious if any one knows of a more efficient way to accomplish what i did because the current trigger set up is quite extensive and a bit of a mess for such a simple animation.

i've attached the story for those who are interested.

thanks.
