Desperados III

As the previous speaker said, it is small creatures that need to be killed (crabs, rats, snakes, frogs). I would like to add a couple of points from my observations:
1) All these animals always appear on the map in certain places. That is, if one rat walks along the road near the bank, then it will always appear there until it is run over.
2) If you have already killed an animal in a certain place once during a mission, then it will no longer appear in that place!! You won't be able to farm here, I checked it personally, even re-downloaded it, no effect))
3) Based on the point above, I concluded that there is a certain number of animals on the map, that is, as many as the developers put them on the map.
4) If you stand next to a place and wait for an animal, then most likely it will not appear, it is probably afraid, so you should put all your heroes away and watch it yourself periodically.

Personally, I completed the trophy in the 8th mission, where everyone was leaving a fun night)) I found exactly 10 animals (1 crab, 4 rats and 5 frogs) and couldn’t find anyone else, I searched the entire map. But that was enough.
-a crab on the shore in the upper left corner of the map;
-rat in the bank area;
-rat in the area where Cooper and Kate woke up;
-rat at the bottom of the map, on the road, just above the dentist;
-rat in the port where 2 Cloaks walk;
-frog in the area where Hector meets the very first enemy at the beginning of the mission;
-frog on the road near the cannon;
-a frog on the road a little to the right of the place where the disguise for Kate hangs;
-a frog on the road a little lower and to the left of the bank, there are still chickens running around there;
-frog in the port on the road, almost reaching Cloaks.

You can only kill chickens and only with the help of Hector's trap
