Skunk - Fire type because of the tail shape. Easy to see the tale as fire and it’s scent gland used as a flamethrower.
Raccoon - Water type because racoons like to wash their food in water, when convenient. Look up videos of people giving them packing peanuts if you want a heartbreak.
Opossum - Grass type because they like to hang out in trees. That tail is prime vine whip material too!
The region would be abnormally high in crystal Pokemon.
