Yeah, the rontos are what I expect he would rant out loud about in reference to Star Wars not supposed to be having dinosaurs (as dewbacks were originally mostly just glorified background detail, not drawing huge attention to themselves), which is what the kid probably picked up on. It is kind of a shame, if you really think about it, that people around Star Wars fans only tend to hear the negative things we rant about the films, rarely getting insight as to what we love about the originals (well, maybe in the middle of a heated rant they'd hear some of the positive feelings, but the negatives would be what they come away remembering).
