If the key is in the full moon effect on mink, then the trump card intended by Inuarashi can not be used that easily because they can only wear it when the full moon appears.
Wanda and Carrot's words seem to indicate that the Minks will be dangerous creatures when the full moon appears. Earlier the full moon was not visible because it was covered in clouds. Since the full moon effect on Mink seems to be re-emphasized by Carrot's statement, it is not impossible we will see the effect immediately.
Caesar once mentioned that the Mink Tribe is a barbaric race that has enormous powers. Surprisingly, the Mink tribe does not seem to have a particular grudge on humans and even seems to welcome the guests who come to remember them until they have a bell of welcome for outside guests.
We know that the Minks have an uncontrollable animal side. An example of Mink dogs who can not help when they meet Brook, Roddy the bull who directly plowing the waving cloth, and Blackback the gorilla that can be soothed with a banana.
Is this what makes the Mink Tribe appear ruthless in the eyes of the layman?
