sentences:  Although the idea for Bloody GIR was confirmed by Ressel not to have surfaced until the episode "Bad, Bad Rubber Piggy", some claim to have found it in earlier episodes of the series, such as "Dark Harvest" and "Attack of the Saucer Morons".Additionally, some people have claimed that Bloody GIR was meant to debut in the episode "GIR Goes Crazy and Stuff", in which GIR was supposed to be covered in blood while floating with the data canister and draining humans, but this directly contradicts Ressel's statements on the matter.Many people believe that Bloody GIR was the reason behind the cancellation of "Invader Zim".
