(I can't believe I'm typing this, but mild spoilers for The Emoji Movie follow.)
There's a recurring joke in the movie about how when a princess whistles, birds appear. It's not funny, but it does have a payoff. As the story lumbers towards its conclusion, we find out Jailbreak, the hacker emoji, actually used to be the princess emoji -- seriously, don't ask -- and she uses her princess powers to summon a winged creature. Guess what form it takes? That's right, the Twitter bird, which Gene can then ride Never-ending Story-style back to his hometown.
If you've read this far into an article about The Emoji Movie, you might be asking yourself, "Do I need to see this movie with my own eyes to prove it's real? Should I too, like Gene, climb aboard a Twitter bird and carry myself to a local theater? Is it worth jacking-in to cyberspace for?" The answer is probably not. Save yourself. Or, as a character in The Emoji Movie suggests at one point, "Go read an e-book!"
