They weren't wind up penguins in Batman Returns
They were wind-up penguins in the Batman Returns Happy Meals.
They also fired missiles, not exploded... was there maybe a different wind up penguin bomb toy in a different part of the movie?
True. Everyone was like 'omg a Batman Returns homage!' on all the websites (its on the imdb trivia section too) and I was like 'er..no..its not'
Yeah, it seemed to be just a generic reference to the Penguin, but not the Batman Returns version.
That's how I took it....but I went to watch a movie, not analyze every passing line of dialogue.....
