Baby WestWorld Is Released In December 15, 1999. In it, Aspen and Sierra have fun at the park, where Gabriel, Brad, Mia, Maddison, Macrae, Brandon, Gaby, Dakota, Dylan, Chloe, and Toby are having fun with their parents, while Mrs. Pluto announces that she is pregnant, making Mr. Pluto extremely overjoyed. Mark starts to baby talk her stomach, but the woman tells him that you can't talk to a baby that hasn't been born yet. The baby's gender is undetermined, but the room of the nursery in World Of Words and the baby's birth in Baby Van Gogh show that it is a girl. However, after that video, bullies used time travel to prevent the baby's conception.
