Alice In Wonderland

[Allogagan]

Slightly off topic but still about Alice in Wonderland related. In the 1951 Disney's Alice in Wonderland when Alice grows in the White Rabbit's house you see one of her legs growing out of the front door and when they show the full house (see attachment) you see the other legs has also grown out of the house. Where exactly is it coming out of? They never show how this legs got there.
