Nine-year-old AAsher loves to dress up and match his favourite characters at Disney World.
In the clip filmed on May 24 in Orlando, AAsher can be seen hiding behind a member of staff and jumping out to scare Donald Duck.
“Donald was so surprised when AAsher jumped out and said 'BOO' that he fell to his knees! Donald was so sweet with him giving him big hugs and even signed a heart to him after fixing his bow tie!” AAsher’s mum told Newsflare.
The pair shared Donald's signature ducktail shake before getting photos together.
"AAsher is non-verbal and it didn’t make one bit of difference. Donald understood him completely and made AAsher feel so special," Aasher's mum explained.
