Collective of the Retconning Crocodiles
The Collective of the Retconning Crocodiles was a malevolent organisation made up of intelligent, time- and dimension-travelling crocodiles.
Nature
The Retconning Crocodiles were believed to dwell in an interstitial dimension known as the Time Sewers, from which they could access whatever other universes they wanted, spontaneously creating manholes that connected the Sewers to the world of their destination.

History
Doctor Sigma mentioned the Collective of the Retconning Crocodiles' Time Sewers as part of a lecture on the various existing methods of interdimensional travel. As an example, he showed images of a Retconning Crocodile using the Sewers to access a natural location where there should not have been any utility manholes, to the puzzlement of a Red-Bearded Gnome.

The Geometron Pentagon once brokered an ill-fated alliance with the “horrible three-dimensional reptiles”, which, after its failure, eroded the population's trust in the Pentagon. (PROSE: Multiversal Mischief) They were also involved in the quest for the Frost King's treasure, as were the Wellsians.
The Crew of the Copper-Colored Cupids had various files on the Crocodiles in their Archives, but they kept disappearing; although Herodotus-724 thought there was a chance they had simply been misplaced, it seemed sadly likely to Bibliophile-962 that the Crocodiles had retconned them out of existence to protect their secrets.
