One: as a sunshine-y ball of CGI designed to appeal to nature’s innocence, Happy is this show’s biggest weapon, with the character’s untarnished positivity hilariously juxtaposed with the over-the-top criminal underworld that Nick gets drawn into.
Happy is amazing for two central reasons.
Two: he’s voiced by Patton Oswalt, who completely sells not only Happy’s whimsy, but also the way the character applies a best-case-scenario outlook to the dark and immoral moments of his burgeoning partnership with Nick.
After waking from a near-death experience, Nick finds he’s now in the company of a winged blue horse named Happy, and though Nick initially assumes Happy’s presence is the result of narcotics and/or alcohol, it’s soon realized that even though Happy is an imaginary friend, he’s anything but a hallucination.
