Climbable Wall

Climbable Walls are a gimmick that appears in Sonic Boom: Rise of Lyric. They are a type of walls that indicate where the player can use Climbing.

Description
The Climbable Walls are vertical walls covered entirely in deep red and rough-edged crystals. Their purpose is to provide ways for Knuckles to traverse the environments in the game's levels using his specific character abilities.

In gameplay, the Climbable Walls indicate which and where on vertical walls that the player is able to utilize Knuckles' Climbing ability to scale walls, meaning that Knuckles is only able to climb on the parts of the walls that are covered in red crystals. To use the Climbable Walls in gameplay, the player just has to jump onto them.

Climbable Walls do not necessarily provide safe passages. Some of them have their path block by breakable obstacles and others have spiked balls, which can cause damage upon contact, attached to them which the player must navigate through.
