You can now raise and nurture Sanrio's Gudetama (the lazy egg) in a Tamagotchi environment. Hatch and take care of Gudetama to determine which version of Gudetama you get! Give Gudetama attention, feed it soy sauce or a tomato and play games so Gudetama doesn't turn into an egg dish! But if that happens, no worries, just start again to see which Gudetama version you raise next! The shell is yellow with Gudetama's face.
