Bob Clones

 were NPC that gave event currency to get prizes. They were appearing on the streets of the Player's Springfield and their Neighbors' Springfields. When the player tapped them, they were getting event currency. There were two different ways to collect them:
 * In the player's own town, they rewarded 7 Gas Masks or 7 Music Notes AND 4 Fertilizer, 4 Corn or 1 Mutant Seed.
 * In their Friend's Towns, they rewarded Gas Masks or Music Notes for the first 90 actions (1 per action).

They were in the Terwilligers 2015 Event and took place of the Mutant Vegetables.

Trivia

 * A maximum of 40 clones could be found in your town at a time.
 * One new clone was spawned every 10 minutes.
 * Farming License is available to double the reward in the player's Friend's Towns.
