The Challenge is over so obtaining the Sugar Skulls or the Display Case isn't possible. Since the Display Case is a locked item in Build Mode, you can't purchase it and it's impossible to unlock it since you can no longer talk to Jasmine to unlock it. I suppose a mod could be used to re-enable talking to Jasmine that will allow the Household to unlock the object and possibly allow obtaining the Sugar Skulls. There are some ways to get the Display Case without cheating or using mods:
- Use Free Build Mode to place the object and then save the room.
- Place a Room or Lot (either created by yourself or downloaded from the Gallery) that includes the Display Case.
- For Get to Work Players, selling and buying it through the Retail Store could work.
Please note that the Display Case will remain locked so you'll need to place a room to "purchase" another Display Case.
Other than using the Gallery or possibly GTW's Retail Store, I do not know if there's a way to obtain the Sugar Skulls without using cheats or mods. I have uploaded a room in the Gallery containing the Display Case and the 9 Skulls for the interaction to obtain the final Skull. However, you do have to manually drag the item to the Inventory for the Skulls since the Collection only registers when the item is placed in the Inventory.
