In "Khrysalis", during the mission "Message in a Bottle", you can meet "Allan GhostDust", who is the representation of an avid Wizard101 player who was able to tour KingsIsle studios due to the Make-A-Wish foundation.

In the town of Marleybone is a character named The Professor, standing infront of a "Telegraph" box, wearing a fedora and a long scarf. Talking to him, he will ask the player if they would like a "Jelly Baby". This is a reference to the Sci-Fi TV series Doctor Who and its protagonist "The Doctor", in particular his 4th incarnation, who wore a fedora, a long scarf and liked to eat "Jelly Babies". The Doctor is also famous for travelling around in a blue Telephone box.
