Gravity Falls - The Legend of The Gobblewonker, Headhunters
The kids ignore their Grunkle to find a sea monster and learn a lesson probably and throw away 16 disposable cameras. Then they discover a wax museum that has been ignored and is cursed. I like that they have started adding some regular townspeople and running jokes with them. Sometimes the randomness is a little predictable, but it is a good show nonetheless.
