[Name] Pox of LeChuck [Source] Tales of Monkey Island [Symptoms] 
The Pox of LeChuck (also named LeChucken Pox in the final episode) is a plague apparent in Tales of Monkey Island that swept across the Caribbean when Guybrush stabbed LeChuck with an enchanted voodoo sword at the Rock of Gelato. This caused LeChuck to be stripped of his voodoo powers, releasing a pandemic that transformed many pirates into green-skinned, foul-mouthed monsters. It also spread to Guybrush's hand, giving it a life of its own (even after being cut off by Morgan LeFlay), as well as infecting his wife, Elaine Marley. The only known cure is La Esponja Grande, which Guybrush embarks on a quest to find after speaking with the Voodoo Lady.
