Click the present for your random gift. I wanted the present to move around and shake until you clicked it, but couldn't make it happen with the required function calls.

Golfed c.onclick=z=()=>{c.width|=0;x.font="16em A";x.fillText(String.fromCodePoint(127873+t*60|0),832,668)};t||z()
u/prplz

Ah i just realized that won't allow you to do the movement you wanted, but there are some other tricks there
u/Agnes

Thanks for the onclick tip! That kind of allows me to do the shaking.

Dynamically swapping the draw order to get proper overlapping. Change i>960 to 1 or 0 to see how this works.
