Short answer: No. Candypoluza is a seasonal event exclusive to the original MySims (Wii, 2007). It does not exist in MySims Kingdom (Wii, 2008).
The sequel shifts focus to kingdom-building across distinct themed islands—Capital, Forest, Desert, and more. You'll tackle RPG-style quests, customize your wand, and recruit NPCs to grow your realm. Seasonal festivals replace the original's Candypoluza event, offering their own rewards and activities.
If you're determined to experience Candypoluza, you'll need to play the first MySims game.
