In the Pokedex, it says "apparently it is staring at something only Gothita can see.". What exactly is Gothita staring at?
In it's Description it says that Gothita observes trainers very carefully. Only Gothita knows what it is staring at so no-one really knows(Not even bulbapedia) so no-one can not give precise answer.
Trainer "Hey Gothita what are you staring at?" Gothita "My imaginary friend mutters under breath he is a lot more interesting than you"
