Aiding and abetting Blink were:
The ever-patient "Auntie," who acts as housekeeper, and who, despite her name was obviously considerably younger than the Colonel.
Rover the dog, who needs to be even more patient as he's often mistaken for lions, bears, rugs or insurance salesmen.
Next-door neighbour Cartright, often the innocent victim of some misunderstanding or other (him being accidentally covered in grass clippings leads Blink to shout approvingly: "Got a monkey to cut the hedge, eh Cartright? Dashed clever idea!")

Sundry nephews and small boys, as motive forces, Greek chorus and/or astonished by-standers
