Where is Stinky?

My children have a pet fly named Stinky. At least once a week or more, a fly gets in my car. About 4 weeks ago K was bored and decided to name the fly Stinky and then call for him when was not in view and then yell at him if he landed on her. M got into that action and now when we get into the car she asks, "Where is Stinky?" or "Where did Stinky go?" The game of Where is Stinky lasts for most of a long car ride. It is cute most of the time. DH S does not find it as fun, which honestly makes it more fun.
