To find Billy, you're heading for Freaky Fields, just to the northeast of the center of the island. This POI is mostly fields and barns - good places to load up on guns and ammo - and one, unassuming white house in the southeast corner. That house is where you're heading.
When you walk through the front door, there's a TV with Billy's face directly ahead of you. That's your target.
Billy will pop out and start attacking you almost immediately. Luckily, he only uses his Spiralized Slicer pickaxe, so he's limited to melee.
Take out Billy, and he'll drop a Boom Billy (that you'll need for another quest - damage opponents with a Boom Billy), a Shield Potion, a couple weapons, and some FlowBerry Fizz.
