great observation ! Unkar Plutt was indeed inspired by the blobfish .There was a small hard back book put out through readers digest called Rey’s survival guide in which she frequently refers to him as the blobfish .It is actually a pretty good read and gives a lot of insight into Rey’s daily life on Jakku .It contains backstory that I feel would have made the novelization of TFA a lot better , but I suspect Alan Dean Foster had a mandate to hold back so Disney could do a double dip into the fans pocket books . I enjoyed the survival guide more than the TFA novel and I loved Foster’s adaptation of the original Star Wars movie that he ghost wrote using the name George Lucas . That one had loads of characterization and world building.
