How To Hack Alexa (Echo Dot) into Big Mouth Billy Bass

Alexa is fun and all, but combining her with animatronics such as the Big Mouth Billy Bass creates a much larger and weirder personality! In this post I'll walk you through how to make an Alexa device out of a Billy Bass toy. This isn't an original idea (kudos to Brian Kane for coming up with this project), but I've tried to make the steps as simple as possible.
