Quackthulhu is a gigantic mutated duck created by Matthew Mercer.

Description[]

Appearance[]

Quackthulhu is a massive, swollen duck-like creature of ill green feathers and flesh, burning red eyes, and four terrible whipping tentacles protruding from its body. A glowing stone that fell as a shooting star is embedded within its back, with dark veins writhing around where it pierces its body.[1]

Biography[]

"The Adventures of the Darrington Brigade" (Sx49)[]

Quackthulu was an ordinary duck until a meteor crashed into its duck pond, implanting itself into his back, and mutating it into a gigantic aberration. The Darrington Brigade killed it after a long, hard-fought battle, removing the meteor to take back to Doolan Tversky for a 10,000 gp reward.
