In the game
In Island Escape, he was just seen behind the Bart's door with a Waka Waka mask and a knife.
In Bart's game, he was in a dark room (when Bart came in) as then the light turn on and saw Sideshow Bob. He had Bart tied on to a chair as he had a helmet on his head. Sideshow didn't wanted to kill Bart, but making him a new member of the Sideshow clan. As then Bart had some last words, he said to Bob, that he wanted to go on a rock concert and Bob saw that Bart likes music, so he wanted to sang to Bart until he was zapped and fell on the floor.
In Bart's second game, he was seen in a room first looking at the monkey, then when Bart shouthed at him, he came after him, but slipt on a banana peel and fell on the ground.
