Chachi (Charles Arcola) has only one POP action figure in his effigy! Character very present in Happy Days, we can hope to see Funko offer more Chachi (Charles Arcola) action figures. In the meantime you can still complete your collection of POPs from the same universe with Richie (Richard Cunningham), of Fonzie (Arthur Herbert Fonzarelli) or the ones of Arnold (Matsuo Takahashi).
