This is my shrine to the Tamagotchi character the Ginjiro-Chi, Ginjiro means guy and chi can be added to the end of any japanese work to mean cute, or sweet.
This is what the Ginjiro-Chi looks like
This is what it looks like on your Tam. 
It was also brought back in the
anglegotchi as the Ginjero angle which looks like this 
The Ginjero-Chi is by far the sweetest Tamagotchi character, it stars in it's own game The Tamagotchi RPG .
To get the Ginjiro-Chi is quite hard, you must get a Maru-Chi with full discipline, treat it really well never let it drop below 1 heart preferably, keep it minimum weight but when it's a tama-chi don't go past 75% discipline.
The Ginjiro-Chi loves to eat Tacos and Lollypops! There is many Ginjiro-Chi Merchandise...
