 In the same way that Dreamworks pokes fun at Disney characters in  _Shrek (2001)_ (qv), Disney/Pixar does the same thing here by  letting Dory in some of her not so bright moments shout, "Pick me!  Pick me!" like Donkey in "Shrek" at the time of departure from  Shreks swamp. Similarly, Dory/Donkey singing and Marlin/Shrek  forbidding them to sing.
