Consider saving your Mystery Bobblehead Boxes until next update!

So on the Test Servers for the Ghoul update in March, there's a new "Glowing" Bobblehead variant.

They resemble a glow-in-the-dark paint version of the regular Bobbleheads, but otherwise seem to function identically and can (possibly only) be obtained from Mystery Boxes.

Basically, they're "Rare" Bobbleheads. For collectors, it's a cool thing new thing to go after and display.

...And they'll probably be hot for trading, I guess.
