Oh My Gush

Oh My Gush is a Challenge in.

Description
During this Challenge, four gushers are added to each available stage during otherwise standard Turf War matches. The gushers act as either columns aiding mobility or stage hazards depending on which team activates them at a time.

Each gusher starts off deactivated, and may be activated by any player regardless of team via being attacked, after which it propels a large amount of ink matching the attacker's team color. After a short period of time, the gushers deactivate. On contact, activated gushers propel players with a matching ink color upwards, whereas players with the opposite ink color are hurt, and may be splatted by them. Inactive gushers may be stood upon.

"Where did all those gushers come from? Might as well make the most of them! Gushers have appeared in the stage! Attack a gusher to make it erupt with your color of ink. You can use them to hide or climb. Both primary and secondary abilities will be enabled."
