Little Brother (Mulan)
Little Brother, the spotted dog from Mulan can briefly be seen in Tarzan.
In Tarzan when Jane brings her father and bodyguard to meet the apes in their habitat, the apes pick up Professor Porter (Janes father), turn him upside down and begin to shake an assortment of random items out of his pockets.
For a couple of seconds viewers can see a white and brown doll fall out of Professor Porters pockets. This doll happens to be Mulan’s pet dog, ‘Little Brother’ from fellow Disney movie, Mulan.
