I think I have worked it all out.
The Frenchman is M. Clousseau, an ancestor of the inspector from the Pink Panther movies, the Iroquois is a friend and personal trainer in a captured British tunic and M Clousseau is saying "Not now Cato".
The evidence for this is the empty threat displayed by the predator Pike fish who is chasing and hunting nothing, whilst in reality,
he would simply sit and wait for his own ambush to provide a meal.
I really like this model .
