This is the first time since the 100th Episode Special from the original series where Steve and Joe appear on screen together.
Before the pitch for a new series, actor Steve Burns suggested his character would succeed as a detective in his adult life. In this episode, we see just that. On top of that, the name of his detective agency, Blues Prints Detective Agency, is a reference to the original title of "Blue's Clues", which was "Blue's Prints".
