From the Disney Parks Blog:
Some lucky Disneyland park guests experienced a very special meet and greet with Mickey Mouse this week.
Mickey, who usually saves his voice for shows and parades, talked with guests and interacted with them in never-before-seen ways! This was part of a process we call “playtesting” as it gives us a chance to develop new concepts with our guests long before they end up in the Parks. “We’re always looking for innovative ways to let guests interact with our beloved characters,” says Disney Imagineer and head of Advanced Development Scott Trowbridge. “And we have many more surprises up our sleeves.”
Since many guests did not have an opportunity to experience this, here’s a short video that shows some of the fun.
