...Located on the western end of the pier, the lush and colorful Inside Out Headquarters will be the future home of Inside Out Emotional Whirlwind! Making its Pixar Pier debut in 2019, this whimsical family-friendly attraction inspired by “Inside Out” will be—not surprisingly—full of emotions.
The new concept art confirms previous reports that the attraction will be re-purposed from Flik's Flyers in A Bugs Land.
