Sir Worth-A-Lot is an enemy in the game Wario: Master of Disguise. They appear in Carpaccio's Lab and Allergia Gardens during Wario's journey there. They appear as golden-armored Sir Lance-A-Lots, having attained this armor by having perfect attendance for 5 years. They act like Sir Lance-A-Lots, but have more HP. They can easily be dealt with by using any attack.
There are two enemy generators in a room of Carpaccio's Lab, which create unlimited Sir Worth-A-Lots.
If you go five years on the force with perfect attendance, you get a snazzy golden armor upgrade. Robots go wild over this stuff.
