The Penguin is considered a criminal mastermind in Gotham City. He plans crimes, but usually doesn't commit them himself - this makes it difficult for Batman to prove that the Penguin planned the crimes.
Oswald had a miserable childhood, and due to his mother's fanaticism, he always carries an umbrella - ones that shoot bullets, spray acid, and do all kinds of nasty things. Most of The Penguin's crimes are bird-related or play on bird-like themes.
The Penguin now runs a casino/bar in Gotham, from which he directs his criminal enterprises. However, Penguin recently decided that he missed both taunting Batman and getting involved personally in his crimes. In this case, he committed various thefts around Gotham, leaving clues to tell Batman that it was the Penguin who committed the crimes. When Batman confronted the Penguin and recorded a confession, Penguin pointed out that unless Batman appeared in court, and revealed his identity, the tape could never be used as evidence. This meant that Batman had to let him go free. This also satisfied Penguin's urge to personally commit some crimes.
