How could I go about making something move to adjacent rooms?

I am trying to make a FNAF game, and Chica's (A character) behavior is that they move randomly to an adjacent room. Bonnie will just teleport to any random room so thats okay, but I would I go about listing possible rooms?

1 thing I thought I can do is to make a value showing the current room, and finding that room in my rooms model, and put values in that room of the surrounding rooms. Is that the right way to do it?
