The lazy egg in our fanart Gudetama Having Fun Sticker is one of the most mysterious characters in the Japanese company Sanrio. The anthropomorphized egg yolk is a sad and lazy individual who lazes about and muses about doing nothing. By the way, the strange egg is Sanrio’s third most profitable character after Hello Kitty and My Melody, and he is only becoming more popular. Let's have some fun with this rolling-on-the-floor egg.
