It occurs to me that Architect Doozer is a very complex character. In "The Cavern of Lost Dreams", he is a very proud character, speaking often of how he outdoes himself with every tower that is built. While in "All Work and All Play", we learn that he was once a rebel and did things his own way. Which I think speaks volumes about his relationship with Cotterpin: he doesn't expect any more or less out of her than he would of himself. So, who else loves this great character?
