The wretched hive of scum and villainy at the center of Star Wars: Galaxy’s Edge in Disneyland is celebrating its proprietor’s birthday with a secret menu interstellar cocktail only available to galactic travelers who know to ask.

Oga’s Cantina at the Anaheim theme park is offering a special off-menu Moscow Mule cocktail in honor of Oga’s birthday available only upon request.

The Blue Mule at Oga’s is made with citrus vodka, blue curacao, pure cane syrup, mule mix and club soda garnished with a lime wheel and candied ginger served over ice.

Oga’s Cantina can be found at the center of the Black Spire Outpost village on the “Star Wars” planet of Batuu, the setting for the twin 14-acre Galaxy’s Edge themed lands at Disneyland and Disney’s Hollywood Studios.

The cantina’s proprietor is Oga Garra, a local crime boss who controls the underworld in Black Spire Outpost, according to the backstory created for the cocktail bar.

Disneyland celebrates Oga’s birthday on July 18-20, but the secret menu birthday cocktail remains available for a limited time if you ask the cantina bartenders.

Oga’s space cocktails range in price from the $15 Jedi Mind Trick to the $18 Bloody Rancor.

Oga’s Cantina at Disneyland currently offers no other off-menu drinks — but this isn’t the first time the Star Wars-themed bars on both coasts have experimented with secret menu items.

The Batuu East version of Oga’s once had a “massively insane” secret menu charcuterie board with four meats, two cheeses, four veggies, pork rinds, flatbread and spreads, according to the Disney Food Blog. The charcuterie board has since moved to the main menu on both coasts as the $21 Happabore Sampler featuring a selection of cured meats, artisan cheeses and crackers.

All drinks at Oga’s Cantina come pre-mixed with bartenders pouring them from a tap and adding garnishes.

The Disney Food Blog investigated reports the Batuu East cantina had a secret menu of blended concoction made from the pre-mixed drinks. The Sith — one of those alleged secret menu concoctions — reportedly combined a Jedi Mind Trick with a Jet Juice, according to the Disney Food Blog.

Oga’s bartenders refused to pour the secret menu blended cocktails — but that didn’t stop the Disney Food Blog from making its own version of The Sith. The resulting combination of the $15 Jedi Mind Trick and $15 Jet Juice turned into a $30 unappetizing mess that was nicknamed the “Bottom of Darth Vader’s Boot.”

“It looks like dirty mop water,” according to the Disney Food Blog. “These drinks were created individually for a reason. Just because you can dump booze together in a cup and drink it combined doesn’t mean you should.”

A more successful food hack combo can be found nearby at the Milk Stand in Galaxy’s Edge where an oh-so-Instagrammable parfait layers together Blue Milk and Green Milk. The Milk Stand has also offered a Toydaria Swirl flavor twist that blends Green Milk with streaks of a Tajin-like chili and a sweet mango base.

Not all of the Star Wars-related secret menu drinks at Disneyland have been limited to Galaxy’s Edge.

The Trader Sam’s Enchanted Tiki Bar bartenders at the Disneyland Hotel created a secret menu cocktail to pay tribute to Baby Yoda from “The Mandalorian.”

The off-menu frothy green cocktail served in a martini glass had pineapple and coconut flavors with blueberries for eyes and lime wedges on the rim for ears.
