GrapaDuck MR4
GrapaDuck / Grapen

A rubbery breed of Ducken with gills and strange plastic webbing on its head and wings. It has many odd habits that Breeders consider disturbing and it doesn't play well with other monsters.

Etymology Edit

Its name is a mistranslation of Grape Ducken, referring to its purple coloring.
