Kawanishi Toyo KA 213 code name (Fido)

The Ka 213 was an unusual aircraft, in it that its payload was most curious.
The 213 was a "Last resort" bomber, designed to drop a load of mad , rabid dogs. Possibly for general tactical annoyance.
The unfortunate reprisal of this idea, was that the dogs would often attack the handlers and crewmen before getting airborne.
