McKay is a time pirate who appears in Oceans Unmoving II[1]
McKay became Bun-bun's first mate on the Bloody Bun following the execution of the previous first mate, "Head-on-his-Shoulders" Wigguns. McKay inherited the nickname "Head-on-his-Shoulders", replacing his previous nickname "Smart-Career-Move".
Like all of Bun-bun's first mates, McKay eventually mutinied and was killed.
