Could this comic speak the truth???
Perhaps, but the sad state of affairs that was the cancellation of Symbionic Titan probable had a lot more to do with the kind of show that it is rather than whether or not there were toys made to promote it.
While Princess Bubblegum and Princess Llana are two great characters, it’s not really fair to say that one should have succeed because the other did. They inhabit different worlds in different shows and nary the two shall meet.
