"TailsTube" is a webseries that began airing on March 22, 2022. Described as a "fun and informative, Tails-hosted show about all things Sonic", the series is hosted by a VTuber version of Miles "Tails" Prower, as he answers questions from fans about the Sonic the Hedgehog franchise, often featuring special guests from throughout the series. The series is notable for explaining various aspects of the series' lore. For example, the first episode debunks a popular fan theory that claims that Sonic's world and Earth are two separate planets, and the fourth episode confirmed the existence of a multiverse in the series, as well as establishing that "Classic Sonic" and "Modern Sonic" are not separate entities from alternate dimensions, instead being the same character's past and future variants. The sixth episode also sees Tails mention Jewel the Beetle and the Restoration, two prominent parts of IDW's Sonic the Hedgehog comic book series, further connecting it to the game series canon.
