Hiro has written up a new program for Baymax that will clear junk data from his memory while he charges. Despite being fully charge, Hiro wishes to test out his new program. He inserts the chip into Baymax, and he goes into sleep mode.
Inside his dream, as Hiro suggested, Baymax wanders around counting sheep, when all the sudden his new junk data program comes online in the form of an evil red sheep. It goes around deleting the sheep until Baymax intervenes. Asking why he is saving this "junk data", Baymax states that Hiro told him to count sheep. Considering Hiro to be junk data, the evil sheep tries to delete Baymax's memories of him. He almost succeeds until Baymax intervenes, stating that Hiro is his friend. Helping him understand that friendship is important, the evil sheep no longer considers Hiro junk data. Wanting to learn more about friendship, the evil ship turns into a good sheep and makes a friend with one of Baymax's dream sheep.
After Baymax comes back online, Hiro removes the program to see how it ran. He inserts it into his computer, and discovers that it has rewrote itself. It is now showing sheep jumping about.
- Unlike the regular shorts, this one consists CGI animation in Baymax's dream created in Unity.
