On page 68 of Star Wars canon adult novel Brotherhood by Mike Chen (2022), Professor Huyang is referenced as being so old that the ancient droid purportedly arrived at the Jedi Temple in a big blue box thousands of years ago before ever taught lightsaber creation. Here a snapshot of the passage:
The aforementioned blue box is reminiscent of The TARDIS, the ship from Doctor Who. An improbable blue box that can move in space and time and is larger on the inside than the outside. The TARDIS resembles a large blue police box from the 1960s. That is why I inquire whether Professor Huyang could have been transferred in The TARDIS.
