There's no fighting. Combat powers do not work.
There are no quests. The closest to this would be turning in candy canes from last year's Holiday Event (will be happening again this December) to the Candy Keeper in the Ski Chalet. CrashPositron (when available) generates a series of scavenger hunt-style "quests," but they're manually run, not automated. Talk to Crash about doing them.
