The Chocolate Shamrock Shake, Shamrock Chocolate Chip Frappé, Shamrock Hot Chocolate, and Shamrock Mocha will join the original Shamrock Shake on the menu, according to a report from Brand Eating.

Shamrock Chocolate Chip Frappé: mocha frappe with whipped topping, green sugar and a drizzle of chocolate syrup.

Shamrock Hot Chocolate: a blend of milk and chocolate syrup, but with the addition of mint syrup, too.
