 According to the DVD, there are some references to Massachusetts in  the film as one of the creators is from Rockport, Massachussetts (a  small town on Cape Ann, about one hour north of Boston). In the  dentists office are two "lighthouse lamps" modeled after the twin  lighthouses on Thatcher Island (just off the coast of Rockport).  Also in the dentists office is a framed picture on the wall of  "Motif Number One", a very frequently photographed (by tourists)  building on a dock in downtown Rockport. Finally, while various sea  creatures are relating Marlins quest across the ocean (which  eventually reaches Nigel the Pelican) one step is a group of  lobsters that speak with Boston accents and slang ("wicked  daahhk")... even though the DVD wrongly says that there are no  lobsters in the oceans around Australia.
