This trophy is earned within Molly's story, which is the first story you will play through in the game. Pick up Molly's diary on the dresser to begin the story.
After you have eaten various things around your room and gone outside you will find yourself as an owl. Navigate yourself so that you can see a rabbit below and hold R2 to swoop down and grab the rabbit. Do this a second time with the larger rabbit and do not miss to earn the trophy.
