Sideshow Bob (non-controllable character)

Sideshow Bob is a unique, non-controllable character in The Simpsons: Tapped Out. There is a 10% chance of him randomly appearing in the player's Springfield.

With the Terwilligers 2015 Event, he could be obtained as a controllable character by completing the Blessings of Guilt quest. In this case the non-controllable version of him doesn't appear anymore in the player's town.

Since the end of the event, he can be obtained anyway by completing the Flaw and Order questline if the player didn't get him during the event.

About
Sideshow Bob is a unique character. He cannot be controlled, but he can be obtained by the player. In the game, there is a 10% chance of Bob appearing randomly, the game claiming that he had escaped from imprisonment. Upon his appearance, Bob will run among the player's Springfield. The player must then tap Bob to apprehend him before he seeks shelter in a building.

Upon apprehending Bob, the player will be awarded a small portion of experience, along with a boost to the Righteousness category of their Conform-O-Meter.

Sideshow Bob will first appear in the player's Springfield at Level 6 along with a task, and will then randomly appear from then on.

Trivia

 * Sideshow Bob's character icon can only be seen either when the player is assigned the task to apprehend him on his first appearance in the game or during the Flaw and Order questline.
 * As of the Whacking Day Update, Sideshow Bob appears more often, the chances increased from 1% to 10%.
 * Snake Jailbird was originally intended to be the criminal who randomly appeared in your Springfield, as images of Snake running and being caught can be found in the game files. However Snake was made a playable character and replaced with Sideshow Bob.
 * He can be caught in Other Springfield every time you enter the city. There is a common farming tactic by exiting and entering Other Springfield repeatedly, whereas every time you enter, you can see him, and catch him rather quickly.
 * There is a glitch where if the player visits Krustyland while Sideshow Bob is in their town, he may appear there as well, where tapping on him will cause the game to crash (as his payout is in cash, not Krustyland Tickets).
