The Rosie Face is a running gag in all of Poyo Rides Franchises, most notably Granny Torrelli. It came from

Rosie Face

Rosie, who's face would grow big whenever something bad happened. This has become a meme throughout the world of Poyo Ride. Many characters use this face when something bad happens, most notably Pardo. Poyo Ride even had a friend who made nintendo school comics, and when the teacher got angry, she had the Rosie face, with some evil eyebrows.
