Pillar

The pillar is a gimmick that appears in Sonic Boom: Fire & Ice. It is a natural post that blocks paths in adventure levels. Alternatively, it can be used as a platform.

Description
Pillars are generally cylinder-shaped posts with an icon of Amy's Hammer hovering in front of them. Their exact design depends on the level: pillars in ice-themed levels are ice posts, while pillars in forest-themed levels are cut tree trunks. When moving, they spin around themselves.

Overview
In gameplay, the pillars bar narrow passages that the player often has to use, preventing them from advancing through the levels. By using Amy's Lift Terrain action however, the player can lower the pillars down to ground level to pass over them. After a few seconds, they will then return to their normal position. However, the player can sometimes stand on top of the pillars when this occurs to hitch a ride to a path above the current one.
