So, this guy (and his family members) has been around for as long as I know. From time to time they'll come up, have a walk about and if they are feeling hungry, they'll drop down into my fish pond and eat my fish.
But we took precautions and we barricaded the top part of the pond and he/she/they couldn't come in anymore(sorry dude).
We have made our peace with them, whenever they are nearby/tries to enter the house we just shoo them away then they'll return after awhile without you knowing.
