01 - Place diced potatoes in large pot of salted water. Bring to boil and cook until fork-tender, approximately 15 minutes.
02 - Drain potatoes and let sit briefly to steam off excess moisture. Mash until completely smooth.
03 - Mix in butter, egg yolks, Parmesan, salt, pepper, and nutmeg until well-combined. Allow to cool enough to handle.
04 - Divide mixture into 12 portions. With clean hands, roll each into oval shape for bunny head. Form two small ear shapes and attach carefully to each head.
05 - Press in two almond slices for ears, two peppercorns or olive pieces for eyes, and one carrot piece for nose on each croquette.
06 - Set up three shallow bowls with flour, beaten eggs, and panko breadcrumbs in separate containers.
07 - Dredge each bunny croquette in flour, dip in egg, then coat thoroughly with panko breadcrumbs.
08 - Heat vegetable oil in deep pan or fryer to 340°F. Fry croquettes in batches, 2-3 minutes per side, until golden brown and crisp. Remove with slotted spoon and drain on paper towels.
09 - Let cool slightly before serving to ensure decorations stay in place.
