Baymax Dreams WEB

The second series of shorts, titled "Baymax Dreams", was released beginning in September 2018. They feature Baymax in "dream" sequences. Unlike the previous shorts, they mix the show's 2D animation with 3D animation created using Unity Technologies' real-time rendering technology.

The first short was uploaded by IGN on September 14, 2018, as an exclusive first look; the following day all three were uploaded by Disney Channel and DisneyNOW's YouTube accounts. The first three "Baymax Dreams" shorts were directed by Simon J. Smith with Disney Television Animation’s creative oversight and a crew of 15 "Made with Unity" team members over 6 months using Unity 2018.2.

A mobile game inspired by the shorts, titled "Big Hero 6: Bedbug Blitz" was also released.

Two new "Baymax Dreams" shorts were released in July 2020 by the official Disney XD account.

On January 28, 2021, a special interactive short titled "Baymax Dreams of Fred's Glitch" was released. A non-interactive version of it was made available on YouTube a week later. A website was also launched.
