The '''Second type glitch''' (not to be confused with the [[List of glitches (Generation I)#Dual-type Pokémon glitch|dual-type Pokémon glitch]]) is a glitch in {{game|Red and Green|s}} and the [[Pokémon Blue Version (Japanese)|Japanese Pokémon Blue]]. It allows the player to transform a Pokémon into another Pokémon equating to the index number of its second type. Without the need of additional glitches, the glitch can be used for obtaining a maximum of 15 unique Pokémon species. More Pokémon are available if the player uses a [[glitch Pokémon]] with an [[List of glitch types|invalid]] second type. The glitch can be used with single-type Pokémon, because internally their "second type" is identical to their first type. It is notable for being one of the first unofficial methods of obtaining {{p|Mew}} in the [[Generation I]], through the use of a pure {{type|Water}} Pokémon, most commonly {{p|Magikarp}}. The glitch predates more popular glitches for obtaining Mew, such as the [[Mew glitch]]. The glitch is exploitable through two known methods. | The '''Second type glitch''' (not to be confused with the [[List of glitches (Generation I)#Dual-type Pokémon glitch|dual-type Pokémon glitch]]) is a glitch in {{game|Red and Green|s}} and the [[Pokémon Blue Version (Japanese)|Japanese Pokémon Blue]].

If the player registers an item using the Select button and closes the menu, the position of the Select button remains registered. Using this oversight, the player is able to swap invalid Pokémon and moves in the place of other Pokémon by entering another menu without opening the menu via the start button. This is the cause of additional glitches from "swapping" values of the game's {{wp|Random-access memory|memory}}. | ||

The first discovered method of the glitch involves pressing the | The first discovered method of the glitch involves pressing the Select button on the thirteenth item, exiting the menu using B,B and then swapping the thirteenth option with the first Pokémon by using the A button. This is possible either through the use of the Pokémon menu in [[Pokémon battle|battle]], or the [[Pokémon Day Care|Day-Care Center]] on {{rt|5|Kanto}}. Coincidentally, one of the altered Pokémon flags forces the player to 'see' Pokémon No. 152. A 152nd entry is possible in the Pokédex due to the fact that there are 19 "seen" and "own" [[Pokédex flags]], and a unique Pokémon is stored for every bit. Due to technical limitations, this means that the game must store a minimum of 152 (19*8) Pokémon. In the Japanese versions, this appears as Missingno. (けつばん) but it appears as either {{p|Scyther}} or {{p|Farfetch'd}} in the English localizations. The reason for this is unknown. | ||

The player must first press the Select button on the fourteenth item, exit the menu using B,B and then swap the fourteenth option with the first Pokémon by using the A button through the Day-Care Center. The Pokémon will then turn into an "A" (the Japanese version of [['M (00)]]) with a glitchy nickname. The player should then ask to receive the "A" from the Day-Care Center, and it will have "grown" to level 1. It should appear in the player's party as the second Pokémon. After swapping the fourteenth item with the first Pokémon through the Day-Care Center again, the player will this time receive a Pokémon depending on the second type of the original Pokémon before exploiting the glitch, while keeping the level 1 "A". | ||
