"Fight at the Museum" is the first segment of the forty-fourth episode of Amphibia.
Anne and the Plantars try to rob a museum to obtain an artifact that may have information for them how to get back to Amphibia. Meanwhile, a dangerous enemy relocates Anne.
Anne has been staying up all night trying to research the concept of alternate universes. This obviously results in her becoming increasingly tired and red eyed. The Plantars do not seem to care about wanting to go back to their world as they simply want to relax and tell Anne that she needs a break from her work. Mrs. Boonchuy offers that seeing as how Anne wants to do research, something she never wanted to do prior, they should all go to the museum and get educated; adding that Anne has been gone for five months and needs to catch up on her school work. Furthermore, she wants them out of the house because somehow they have left slime all over the place and she wants to clean it.
Anne and the Plantars are dropped off at the Natural History Museum and are taken in by all the sights. As Hop Pop begins to notice that Anne is becoming paranoid, they come across an ancient jar that looks like it came from Amphibia. As they inspect it, they are suddenly greeted by Dr. Jan, an extraterrestrial and cryptid obsessed curator who notices their keen interest in the jar. She believes that the jar depicts people worshipping a frog like deity whom she believes is extraterrestrial in origin. As she offers to go over it more, Anne turns her away, upsetting the Plantars. Anne instead convinces them that they should sneak into the museum at night and steal the artifact.
Anne and the Plantars manage to sneak into the museum by tricking the gullible guards and Sprig takes out the cameras. However, the Cloak-Bot picks up on their location and bursts into the museum where a fight breaks out. During the commotion, Dr. Jan and the security guards break in and witness the entire scene. Needing to stay discreet, the Cloak-Bot flees. Dr. Jan turns the security team away and immediately accepts the Plantars' presence with Anne finally learning to trust her. Dr. Jan offers to look at the jar and in return Anne get some shut eye as she was drowsy the majority of their adventure. The next day, Dr. Jan shines a black light over the jar, based on Anne's suggestion, and discovers a hidden message.
