Tube

Tubes are a gimmick that appears in Sonic Boom: Rise of Lyric. Entering such an object will quickly send the player to another location.

Description
Basically, the Tubes are big pipes, large enough for any member of Team Sonic to fit inside them and hang from either the walls or roof. Their design and coloration depends on the level: in Lyric's Tomb they are grey with golden mouths and openings, in Ocean Purification Plant they are like glass pipe with green liquid flowing through them and in Lyric’s Lair they are completely black with red outlines.

When the player enters the entrance of a Tube, the playable character will be sucked into it and move through it at high speed. The playable character will then be deposited in a different area, making the Tubes a form of shortcuts through the game's levels. In most cases, the Tubes allow the player to enter areas they cannot otherwise reach, but they can also serve as shortcuts back to an earlier point in the level so the player does not have to take the long way back when having to solve a far-away puzzle. However, the player cannot travel through the Tubes in the opposite direction, so they are one-way only.

In most cases, the Tubes are ready for use when the player finds them. However, some require that the player has solve a puzzle earlier on before they become operational.
