Belle Is Jane’s Grandmother
When you spot a character from another Disney movie in the movie you’re watching, you could just accept it’s a cute reference. Or, you could build an entire theory around it. In this case, in Tarzan, you can clearly see a tea set that looks just like Mrs. Potts and Chip from Beauty and the Beast. On top of that, Jane from Tarzan does bear a striking similarity to Belle from Beauty in the Beast. Perhaps Belle is her grandmother?
