You can easily farm this trophy with little effort. First select the monkey AiAi, select motion sensor controls, load up the beginner stage 1-1. Now place your Vita at an angle that allows the monkey to roll right into the goal. Once you get the angle right, place some stacks of paper or a mouse pad under your Vita and let the game play itself for a while. Be sure to check on your Vita so that it doesn't go to sleep on you!
