* RoleReprise: The only actor to return is [[spoiler:Corey Burton, the VA for Argost]].
* ScrewedByTheNetwork: The show was moved around on the schedule every few months, and new episodes were rarely advertised. As a result, only diehard fans could actually keep track of it. And if you missed an episode you were pretty much out of luck due to lack of reruns.
* ViralMarketing: [[https://www.youtube.com/watch?v=d84CVRXTTQQ Early ads for the show]] were just live action [[JitterCam shakycam footage]] with CGI cryptids that had the [=URL=] cryptidsarereal.com at the end. Later ads used the same footage from the previous ads mishmashed together with Argost's voice-over advertising Weird World. They eventually advertised the show itself about a month or two before its premiere.
* WhatCouldHaveBeen:
** The show's creator originally pitched it as the adventures of three animal heroes (all of them previously thought to be mythical in RealLife, like the okapi) as they prevented an evil dodo bird from exposing the existence of other cryptids. Nobody wanted the show like that, so he reworked it heavily into what we know today.
** At some point in the development, the heroes were going to be "anti-detectives", working to keep the existence of cryptids secret from the public. This would have introduced more moral grayness into their dynamic with Argost, who sought ToUnmasqueTheWorld. This aspect apparently got dropped at some point, as the Saturdays don't seem overly concerned about hiding cryptids in the final draft.
