Gusher

Gushers are one of the mechanics in Octo Valley, specifically in the level Gusher Gauntlet.

Description
Initially, Gushers appear to be stationary, circular, silver grates adorned with a red knob. Upon being sprayed by ink, a large column of that ink color erupts from the platform, carrying all objects, including Inklings, to the top.

Usage
Gushers can be activated by the player firing ink directly on their surface.
