A userscript to replace FiveThirtyEight's new mascot with a familiar friend...
Because Fivey reminds me of SatAM Tails, and because it made me laugh.
I recommend using Tampermonkey (Chrome) (Firefox), since that's what I tested it on, although it should work with Scriptish or Greasemonkey as well. Once you've installed Tampermonkey (or whichever userscript manager you prefer), you can install the script by clicking here.
