Dann Florek (Don Cragen) stated in numerous interviews that Mushrooms is one of his favorite episodes.
The episode title, Mushrooms, is a reference to the classic 1980 video game, Centipede, produced by Atari. In the game, the player would shoot at centipedes descending upon them through a field of mushrooms, which would frequently be hit instead. This is also referenced in the show's dialogue.
This episode was inspired by real-life cases of young children hit by stray bullets.
