Non-canonical imaginizer
The non-canonical imaginizer was a device invented by Professor Awesome in the Parallax Universe. A “strange device”, it could, at the push of a button, project clear images of past events onto the fourth wall, even if they had not actually been filmed by anybody. Kim used it to project a recording of the events surrounding Jenny Everywhere's second encounter with the Puritan Streaker, over Jenny's prior objections that the story couldn't, or rather shouldn't, be told.

Behind the scenes
On the Jenny Everywhere Discord, Scott Sanford highlighted “the semantic ambiguity about the ‘non-canonical imaginizer’[: it] could be an imaginizer that imagines non-canonical events, or an imaginizer that is non-canonical and won't appear outside April Fools' Day tales”. He also confirmed the implication that it works by “projecting pictures onto the fourth wall”.
