Kvack is
Hagar the Horrible's family's
cute pet duck. It's also the
noise he makes: "
quack" with a
Norse accent. Kvack wears a
horned Viking helmet and is quite
expressive despite his
monosyllabic vocabulary.
Snert is the other
pet of the
family.
Dik Browne created the character and his son
Chris Browne is the current
writer/
artist.
