The Doorknob

The Doorknob is the main entrance to Wonderland and a character in the Disney film Alice in Wonderland. He lies at the very end of the rabbit hole that Alice fell through. Due to his small size, the only way to enter him is to drink from a special bottle of multi-flavored liquid that will shrink the drinker in size, the drinker also needs the key to open the Doorknob which is located on the same table as the liquid.
