It’s a jolly holiday with Dick!

Iconic actor Dick Van Dyke celebrated his 90th birthday on Saturday, and Disney pulled out all the stops to honor one of their greatest stars.

The Mary Poppins actor visited Disneyland, where he rode in a special cavalcade held in his honor while park guests sang “Happy Birthday.”

The real show, however, happened at Los Angeles shopping center The Grove, when Van Dyke was surprised with a flash mob.

The dancers, who performed in costume as his Poppins character Burt, danced to tunes from the 1964 movie musical like “Supercalifragilisticexpialidocious.”

Van Dyke watched the performance from above before joining the group below to lead a sing-along to “Let’s Go Fly a Kite.”

At Disneyland, a special silhouette of his chimney sweep character was revealed in the Anaheim, California, park’s Jolly Holiday Bakery Cafe, a theme restaurant.

The star also performed a few songs with his a cappella quartet, the Vantastix.

“I am very grateful that at 90 years old, I can still go out and play,” Van Dyke tweeted on Sunday.

Van Dyke previously told PEOPLE that he has no plans to act his age, and said “I’m still singing and tap dancing.”

In fact, the star just published a book called Keep Moving: And Other Tips and Truths About Aging which offers advice to seniors on how to keep fit.
