The scrambled Bulbasaur are glitch Pokémon in Pokémon Red, Blue, and Yellow which have front sprites that appear as a corrupted tall version of Bulbasaur's sprite much like a Bulbasaur statue.
There are three known variations of the scrambled Bulbasaur in English versions, including glitch Pokémon /PkMn ▼PkMn and Glitch Pokémon (0xEB) in Pokémon Red and Blue (Dodrio hybrids), as well as ゥ 4- 4 in Pokémon Yellow (an Articuno hybrd).
Since /PkMn ▼PkMn and Glitch Pokémon (0xEB) both share the same family and an index number greater than 0x98, they both have the same sprite sourced from 0D:4000 (Bulbasaur's sprite), but with dimensions of 7x7 instead of 5x5; which is the cause of the glitchy sprite.
ゥ 4- 4 has its sprite sourced from 0B:4000, also with dimensions of 7x7 instead of 5x5. Like in Red/Blue, the sprite maps to Bulbasaur but the wrong dimensions of 7x7 cause the sprite to appear glitchy.
/PkMn ▼PkMn and Glitch Pokémon (0xEB)'s front sprite in Red/Blue.
ゥ 4- 4's front sprite in Yellow.
Scrambled Bulbasaur may also refer to Bulbasaur affected by the inverted sprites glitch, especially those from ZZAZZ glitch corruption.
