From Bikini Bottom to Monte-Carlo!

While wearing coordinating navy outfits alongside their father, the 4-year-old twins had an opportunity to meetSpongeBob SquarePantsand Patrick Star on the yellow carpet in Monaco, in honor of the television show’s 20th anniversary.

Prince Jacques, who sported a navy polo and matching striped shorts, was very eager to meet the large pink starfish — instantly going in for a big hug.

In a separate photo, the little boy was captured beaming beneath Patrick Star, who kept his hands on Jacques’ shoulders.

Princess Gabriella, on the other hand, appeared to be a bit more shy when it came to meeting the giant mascots.

The little girl, wearing a navy polo dress, kept her distance and often leaned into her father who was kneeling down for comfort.

She seemed to feel more at ease when she was handed a small yellow bouquet of roses.

For the event, Prince Albert, 61, wore a light blue striped button-down, khakis, and a navy blazer that adorably matched his twins.

“Celebrating the first ever Family Day with my children and honoring the legacy of Stephen Hillenburg, creator of SpongeBob and one of the very first Princess Grace Award winners, was the culmination of an extraordinary television festival.”

Festival-goers had a chance to attend a special screening of the first SpongeBob SquarePants episode from May 1999, as well as the most recent one, shown at the Principality of Monaco’s Forum Grimaldi during Sunday’s event.

Prince Albert also helped kick off the four-day festival on Friday during an opening ceremony at the Forum Grimaldi.

Noticeably missing from the sweet family outing, however, was Prince Albert’s wife and the twins’ mother,Princess Charlene.

Though she was not present on Sunday, the former Olympic swimmer, 41, was spotted just one day earlier at the Circuit de la Sarthe raceway in France, waving the national flag to symbolize the start of the annual 24 Hours of Le Mans race.

Prince Jacques and Princess Gabriella have been world travelers as of late, jetting off to several destinations alongside their parents.

In February, the twins headed to a private game reserve in South Africa with their mother and got close-up views of lions, zebras, giraffes, hippos, rhinos and more.

The reserve excursion, which occurred over the children’s winter school break, fulfilled a long-expressed wish of Charlene’s to share her home continent (she was born in Zimbabwe and raised in South Africa) with her two children.
