About
Here are the animated icons from the game files. Internally, they are stored as 16 still images / frames, so they have been turned into animated PNGs / GIFs with a delay of 100ms in between frames.
Clicking on any of the animated icons gives you the option to download it in either APNG or GIF format.
If you think the timings look off, you can use other APNG or GIF editing tools to change the speed.
