Smurfette is also available on the Mountain, but she costs 35 instead of 30 , like the village, she can make nearby smurfs swoon for XP every few hours. But in the mountain, she gives a 20% XP bonus from crystals(you must have Grandpa Smurf's Hut), you can also buy her tower that costs 10 to transform her into her princess costume, this transformation increases the XP awarded by the swooning smurfs.
Aswell as the Mountain, she is also available on the Swoof Planet, she costs 30 like her original price in the village, she can also make the smurfs swoon in space, including the swoofs. In space, you can buy her throne that costs 10 to transform her into her Cleopatra costume, this transformation increases XP earned by swooning smurfs and swoofs. It also causes the swoofs to perform a new dance.
Smurfette is also available on the Island, she costs 30 like the village, but you need to have her already purchased on the village in order to buy her on the Island. In the Island, she has a minigame instead of the heart floating above her head in most of the locations. The way the mimigame works is by simply tapping on her hut when it has a heart floating above it, then it will ask you if you want to play it, once you tap "Yes", the minigame will start, all the smurfs on the Island will start to swoon, and it is your job to tap on them to get them back to work while Smurfette is sunbathing, once the seconds are up, everything will go back to normal, even the swooning smurfs that you missed on the Island. You can buy her transformation crystal for 10 to transform her into a prehistoric costume, once in her costume, the XP the swooning smurfs give you in her minigame will be increased.
