Some new 13th season episodes have come to light:

And They Painted Dairies On His Coffin ★★
Five-O investigates the murder of a milkman after some customers complained that he delivered their bottles of milk and cream at odd hours of the day, leaving them out in the hot sun.

The Cock Struck Twelve ★★
Chucho, the champion fighting rooster owned by Benny Apa in S01E12, "Pray Love Remember, Pray Love Remember," escapes from a poultry processing plant and goes after people who placed bets on him in the past. In the United Kingdom, the DVDs containing this episode have all the cockfighting scenes removed, plus those where Five-O is baffled because all of Chucho's victims have their eyes pecked out.

The Year Of The Hoarse ★★★
McGarrett loses his voice from screaming at Kimo Carew, who he considers to be totally incompetent. Doc Bergman tells McGarrett that he has to take at least a year off work, but, of course, the Five-O chief cannot sit still.
