This afternoon at Disneyland, Mickey Mouse and Minnie Mouse were joined by Disneyland Resort ambassadors, dozens of Disney characters, and a bunch of fans to celebrate a special 90th birthday moment.

The festivities kicked off with a cavalcade through Disneyland — right on down the middle of Main Street, USA — and ended at Town Square with a special happy birthday sing-along… and of course, streamers.

The entire Walt Disney Company is embarking on a year-long celebration in 2019 commemorating the 90th anniversary of Mickey and Minnie Mouse’s first debut in “Steamboat Willie” in 1928.
