The Tails Vent is a large fan creating a straight gust of wind from its fan. In most cases, they are positioned on the ground, but they can also be set on walls and roofs
The Tails Vent serves as a way for the player to traverse the areas using Tails' Hover ability. By using Hover inside these vents' drafts, Tails will move in the direction of said drafts. For example, using Hover within an upward draft will make Tails rise into the air, allowing access to areas out of jumping range. Ceasing Hover or moving outside the drafts will halt Tails' momentum. Also, a network of vents placed on walls and roofs so their drafts intersects will form midair paths that a hovering Tails automatically moves through.
Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, these vents are referred to as Tails Vents. In this game, the Tails Vents have a thick yellow and black-striped plating surrounding their fan. Exclusive to Sonic Boom: Rise of Lyric, the Tails Vents can sometimes move around on their own to help Tails keep his altitude when moving around in midair. Others can first be activated after completing a puzzle.
Sonic Boom: Shattered Crystal
In Sonic Boom: Shattered Crystal, the Tails Vents are referred to as Air Vents. Unlike their armored design in Sonic Boom: Rise of Lyric, the Air Vents have no plating in this game. Instead, they have a blue and yellow ring around them and a grid covering the fan.
Sonic Boom: Fire & Ice
In Sonic Boom: Fire & Ice, the Tails Vents have the same design they had in Sonic Boom: Shattered Crystal. This gimmick is particularly essential when facing Sticky Situation, where the player has to fly between vanishing Tails Vents while avoided obstacles to stay above a tar pit.
