Deprived of Eternal Sleep

Deprived of eternal sleep turns the Three-Tails arc toward its captured-beast premise: the tailed beast stirred from dormancy, Orochimaru's faction maneuvering to claim it, and the team racing to contain a force that shouldn't be awake. The episode is filler doing tailed-beast spectacle, the Three-Tails a rare host-less beast the anime can use freely. Sealed entirely within its own arc, it keeps the cast busy with a genuine threat during the manga's lead time, harming and changing nothing in the canon timeline.
