Wublins

Big Blue Bubble released a short teaser video on March 16th, 2016, and on March 17, 2016 showing a neon sign, reading "Wake up the Wublins" (or, alternately, #WakeUpTheWublins), lighting up with a sizzle of electricity and a roll of thunder.

It isn't yet known who or what the Wublins are. The video suggests that they have something to do with electricity, like the Wubbox.
