Brainworm Rot Type B, while not as deadly as its counterpart Brainworm Rot Type A, possessed the dangerous ability to quickly transform into the more virulent Type A if not properly controlled. It is classified as a variation of the broader Brainrot Plague.
Around 1 ABY, this novel Type B strain was found flourishing within various creature habitats. A focused initiative was launched on Tatooine, led by Wol Cabasshite Ambassador [Lurll], with the goal of eradicating all infected creatures and preventing further dissemination.
Similar to Brainworm Rot Type C, it is believed that this specific ailment originated on Neimoidia.
