Capture the Bandit Piggies on the loose in the Wanted Pigs event, and turn them in for the reward!
How does the event work?
To claim the bounty, you must find and capture three Wanted pigs to claim the rewards. When you see a pig skull above a level button on the map, this indicates that you can find a Wanted Pig on that level. You can capture the pig by completing that level successfully. Once the pig has been captured, you will receive your reward, and then you can find and capture the next one.
If you fail or quit a level instead, the Wanted pig will escape to another level. Once you reach that level, you can try to capture it again.
