I wish that all who vote this and I will receive a pair of dimensional scissors (similar to the ones used by Star in SVTFOE) capable of entering fictional worlds in their mail/PO box within a month. The person entering can also change their species/appearance to blend in more with the characters, and any alterations to canon will take place within an alternate universe, meaning they won't change anything with the original story. To enter, they just have to focus on what world to go in whilst cutting in a vertical line. When the person returns, no time will have passed in our world and while they can keep any object they bring back with them, they will only be seen as novelty recreations of it to other people. Upon returning, the person will also become a human being/regain their physical appearance. If you do it in public, people will forget seeing you open the portal the second you step out of it.
