The Pewter Museum of Science (Japanese: ニビ科学博物館Nibi Museum of Science) is located in the north side of Pewter City, Kanto, and is one of the city's main attractions. The Pewter Museum of Science hosts a wide range of attractions and exhibits, largely based around space and Fossil exploration. The museum holds a huge collection of artifacts, including rocks from the moon, space shuttles, and Fossils of ancient Pokémon. The admission is 50 for a child's ticket.
In the games
There are two floors to explore in the Pewter Museum of Science. The first floor holds the front desk, and a Fossil exhibit containing the Fossils of Aerodactyl and Kabutops. MissingNo. may use these sprites, depending on its index number. The second floor hosts a space exhibit, featuring a Space Shuttle and Moon Stone that fell onto Mt. Moon. The player is able to explore the museum at any time, after paying the 50 admission fee.
In Generation IV, the museum is open for business, but the major exhibitions are elsewhere, so entry is free. There is only one floor in this generation. There is a scientist in the museum who will revive a player's Fossils, much like the scientist at the Cinnabar Lab in GenerationsI, III, and VII. This is due to the fact that Fossils can be found under rocks using Rock Smash, unlike in Generation II, where players were required to transfer Fossil Pokémon from the Generation I games using the Time Capsule. Steven Stone, former Champion of the Hoenn region, will also appear here after the player has received a Hoenn starter Pokémon from him at the Silph Co., inspecting a meteorite exhibit.
The Kabutops Fossil
The Aerodactyl Fossil
The Pewter Museum of Science hosts a wide array of different exhibits and attractions. The first floor contains Fossil exhibits, including Fossils of Aerodactyl and Kabutops, the rare, prehistoric Pokémon. The second floor has a space exhibit featuring a model of a Space Shuttle, and a rock, most likely a Moon Stone, that fell onto Mt. Moon in the form of a meteorite. In Generation VII, the Aerodactyl fossil is replaced with a cast model.
In the Generation I games and their Generation III remakes, an old man on the second floor of the museum states: "July 20, 1969! Humankind first set foot on the moon that day. I bought a color TV just so I could watch that news." July 20, 1969 was indeed the date that humans first landed on Earth's Moon in the real world. In Generation VII, he also talks about humankind's plans to set foot on Mars.
Enigma Stone event
In HeartGold and SoulSilver, if the event item, Enigma Stone, is taken to the Pewter Museum of Science, traveling Pokémon Champion Steven Stone will have a researcher from the museum examine the stone. The researcher then discovers that it is really the Soul Dew, an item said to be the crystallized souls of Latias and Latios. After this brief encounter, depending on the game version, one of the twin dragons will appear outside of the Museum, giving the player an opportunity to capture it. If the player does not engage in a battle with the Latios or Latias, it will remain there until the player has done so.
The museum was later rebuilt, and during the invasion of the armies of the Elite Four in the Yellow chapter, Brock had one of his Geodude protect a Kabuto kept there. After the ordeal, Brock took Kabuto under his ownership and later evolved it into a Kabutops.
In the Generation I games, the plaque accompanying the space shuttle model reads "Space Shuttle Columbia"; however, in the remakes, the plaque simply reads "Space Shuttle". This is probably due to the fact that on February 1, 2003, the real Space Shuttle Columbia disintegrated upon re-entry during its 28th mission, killing all seven crew members. The reference to Space Shuttle Columbia was kept in the Japanese version of the Generation III games, but was removed in Generation VII.
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, if the player brings a Pokémon with an evolutionary family member that evolves by Moon Stone near the Moon Stone on 2F, it will stop following the player and stare at it. Similarly, if the player brings a Kabutops near the Kabutops fossil, it will stop walking and stare at the fossil.
