Continuity mistake: When they're handing out roses for the second time, when Jimmy gets his rose, we can see Craig at his left, having one too. But in the next shot, when they tell the ones that didn't get a rose to go home, Craig doesn't have a rose and has been eliminated from the competition.
Continuity mistake: In the very beginning, Butters walks in after Cartman, Kyle and Stan talk about replacing him. Butters and Cartman sit down and talk. Firstly, pay attention to the 'Cow Day' banner behind Cartman. After the camera goes from Cartman talking to Butters then back to Cartman, a letter S is now on the banner. It now reads 'Cow Days.' During the same sequence, look behind Butters. You can see Peter Panda on what looks like a toy box. After a few cuts from Cartman to Butters, now all of a sudden, Clyde Frog is next to Peter Panda on the box.
Answer: He appears in at least 5 other episodes, but usually just as a background character. He can be seen at Cartman's party in "Immaginationland". He was also one of the kids trying out to replace Butters in the "Professor Chaos" episode.
