When the player first visits the museum, it has been taken over by Team MagmaROR/AquaSEAS.
One of the Team MagmaROR/Team Aqua GruntsSEAS visiting the museum, the same one that the player had beaten in Petalburg Woods and Rusturf Tunnel, gives the player TM46 (Thief). The Grunt stays in the museum (even after the player defeats his colleagues on the second floor) until he gives the player the TM and runs off immediately after giving it to them.
When the player first visits the second floor, they are challenged by two members of the villainous team.
In Pokémon Emerald, when the player leaves the museum after defeating the Team Aqua members inside, Scott approaches the player to ask them who defeated Team Aqua.
The first floor contains information about the sea in the form of seven exhibits. There is also a reporter who asks the player to tell him a story about Pokémon. This report will later be aired on TV.
On the second floor, there are various exhibits, including models of the Hoenn region and several cruise ships including the Royal UnovaORAS and the S.S. Anne.

Ash and Max visited the Oceanic Museum in The Spheal of Approval, where they met Captain Stern, who was analyzing a heat-affected rock sample from the ocean floor. During their visit, Team Magma tried to steal the stone sample, though Ash and Captain Stern intervened. During the squabble, the sample broke into two pieces, with Team Magma escaping with the larger portion. Captain Stern was left with the smaller fragment, though it was still sufficient enough for his research.
Marius often frequents the museum because of his passion for research and Water Pokémon. His favorite exhibits are the models on display, including those of a submarine and several Pokémon.
Trivia
The museum's theme is a remix of the song heard on the S.S. Anne.
The museum can be entered free of charge before Team Magma or Team Aqua leave, as the reception believes that the player is part of their group. However, it only works if the player lacks the $50 fee, which will prompt the receptionist to believe that the player is part of either Team Magma or Team Aqua.
