So Alex hersch said that there will be 3 seasons and those three seasons will play out over the three months of summer and when season three is done summer is over and he said at the end of season 1(If you go to anime flavor and click on gravity falls it has a episode 10 so there might be 10 episodes)there will be a HUGE cliffhanger that will BLOW some kids minds.So in one of those seasons there may be a episode about merpeople.
