The episode, suitably titled "Surprise," is set to stream on Disney+ at 12 a.m. PT Sunday. It will also air on Disney Junior at 7 a.m. PT and on the Disney Channel at 7:30 a.m. PT, with multiple re-airings throughout the day.
The series follows Bluey, a lovable Blue Heeler dog who lives with her Mum, Dad and little sister, Bingo. Just last week, the normally seven-minute show premiered a 28-minute special, "The Sign," which dealt with the family possibly moving out of their home.
"Bluey" is written and created by Joe Brumm and is starting this year as the most-streamed series across all audiences.
The Walt Disney Company is the parent company of Disney Junior, Disney Channel, Disney Plus and this ABC station.
