Fishie Doggie

   Fishie Doggie was originated when Bushcraft Medic showed Shrubskill Nurse around a room he was in during a Skype call in reality. On the top shelf in the left corner near his desk, there is a plush dog that wears a small pilot helmet and sits in a fish bowl. 

This small dog has been mentioned often in real life, and is believed to make his first appearance as a minor character when the first episode of the show airs. It's a possibility that he will end up having one cameo appearance per episode.
