I could be wrong about this, but I think that Charlie and Lola is a British cartoon that the Disney Channel licenses, so they probably don't have the rights for merchandising and theme park development. There was none there when I went last December.
However, my DD6 did manage to get a Charlie and Lola book from the library. I'm not sure which came first, the books or the cartoon, but the artwork is remarkable similar if the books came first. You might find those available.
