Place the eggs in a large saucepan and cover with cold water. Bring to a boil, then immediately cover the pan and remove it from the heat. Allow the eggs to cook in the hot water for 11 minutes. After 11 minutes, drain the water and rinse the eggs with very cold water for a minute or two to stop the cooking process. Peel the boiled eggs and cut them in half lengthwise.
Remove the egg yolks and place them in a bowl. Mash the yolks with a fork until they have the texture of very fine crumbles. Add the guacamole, and salt and mix until evenly combined.
To make the Baby Yoda eggs, fill 8 of the egg whites with the guacamole filling. Slice the other egg whites in ½. Place one ½ an egg white on top of the filled egg whites. Place 2 peppercorns as eyes into the exposed filling. Place 2 pieces of celery on the outsides of the face of Baby Yoda for ears.
