The Winter Queen Treasure Island

The primary motivation for completion of any Treasure Island is the premium Machine or Animal offered by the Trader for those who did not obtain it in the past and the NEW Machine or Animal given with 1100 Stars.  

In this instance, the Trader offers the Parfait Machine.  If you have it, you can claim 1000 Energy instead.

The new Machine is a Candied Skewer Machine at 1100 Stars.  The translation is poor here as obviously the Machime itself is not Candied but the products are.  In any event, the products tend to be demanded nowadays, so you may consider doing the Treasure Island Activities.  

Although the new Machine can be claimed at 1100 Stars' the last toy needed to claim the final Reward from the Trader usually is found on the second to the last map area.  I will confirm the location when I reach it.

Fire is made in the Fireplace using 2 Blazing Bloom and 2 Branch for each.
