The Tales of Agrabah update has finally arrived in and with it, two new villagers, Aladdin and Princess Jasmine, need your help getting back home.
To bring them to the valley, you'll first need to venture into the new Aladdin realm in the Dreamlight Castle. To unlock the Aladdin realm door, you'll need 15,000 Dreamlight.
If you don't have enough, you can earn more through completing dreamlight duties or by crafting it using Dream Shards. Note that the new Floating Islands will also each cost 15,000 Dreamlight, and crafting Tiana's Slow Cooker requires some as well, so ensure you don't accidentally spend it elsewhere first.
Once you have enough Dreamlight to unlock the door with Merlin, head inside the Aladdin door to be transported to Agrabah. When you arrive, you'll be just outside the city walls, and as you approach, you'll find that Jasmine is separated from you by rocks you can't break.
This is not a glitch: you need to find another way around it. Head up the plank to the left of you and interact with another to create a path.
