- The Profit Bird description notes that making a game with a bird in it makes it instantly popular, alluding to the success of Angry Birds (which the Profit Bird is often compared to) and Tiny Wings (the Profit Bird Flash uses is blue, making it look even more like the Tiny Wings bird). While Jetpack Joyride is popular too, it's less to do with the Profit Bird in this case. Even Flappy Bird gets a shout out later on, with the Zappy Bird Event. It has Barry riding bird through an infinite corridor of zappers, placed in similar fashion as pipes and getting hit by them is an instant game over, though Unlike Flappy Bird, however, you can touch floor and celling. There's also an achievement called "Angry Wings" for getting the Profit Bird twice in one run.
