Pintail's Colleague is a male anthropomorphic duck.
Description[]
This old bearded scientist worked alongside Professor Pintail at Duckburg's Planetarium in 1964. Together, they briefly thought they had discovered a new planet, and, wanting to get a second opinion, they invaded Ludwig von Drake's home and literally drove him from his bed and to the observatory — where the Austrian genius informed them that they had been gawking at a dust-speck on the telescope lens.
Behind the scenes[]
Pintail's Colleague appears in the 1964 story Injun Expert.
