"Snozzberries? Who ever heard of a snozzberry?" is from Willy Wonka and the Chocolate Factory, and she does a brilliant Veruca Salt voice to go with it
There's also "I must break you" in the final boss' mid-match screens, which is appropriately from Rocky IV. And as it hasn't been mentioned yet, the intro to level 2-1 with Mandy is a reference to Total Recall.
