When you've unlocked the door to the Wonderland realm with 15,000 Dreamlight, you'll be able to begin your quest to unlock Alice in Dreamlight Valley. But getting into the Wonderland realm isn't as straightforward as unlocking the door in the Dream Castle and walking in like other realms. There's a little more Wonderland magic in this quest.
Once you've gotten rid of the Night Thorns, the door will shrink down and a white rabbit will run out. Merlin will say you should go after it, and you'll need to chase it around the valley before falling into a rabbit hole and finding yourself in Wonderland. You'll meet Alice as soon as you're in, but you'll have to complete her quests before you can invite her to your valley.
