If you feel a little bit lonely on your daily commute, you might be surprised to know that you are not alone because there might be a playful monster sitting beside you.
Don’t worry though, because these monsters seem friendly enough! They like cuddling up to you when you sleep and hitching a ride in your bag. They also like looking at your phone screen and also listening to your music.
Since 2011 Ben Rubin has been busy drawing this cute doodle series titled Subway Doodles on his iPad to pass the time during his subway commute from Brooklyn to Manhattan.
