Decoy Squad Five was clone squad that specialized in disguise. Many of them disguised themselves as Jedi, and tried to kill Yoda and Obi-Wan. They apparently tried to kill the remaining Jedi who tried to return to the Jedi Temple. They were so happy with their successful mission and for having killed the Jedi, that they threw a party. The squad was killed by Yoda and Obi-Wan, when they came to the temple.
