Complete 5 Seasonal Smashable ChallengesIf you head to the Festival Playlist in the start menu, you'll see a ton of different events to complete throughout the season. Things like races, certain PR events, and so on. In the Forzathon daily challenges though you'll often see what Playground Games call 'seasonal smashable challenges', i.e. No Signal: Smash 5 Phonebooths. So, basically complete five of these and you'll get this achievement.
