Copy Vortex. Ybrik begins to inhale everything within a 30 ft. cone in front of it. Everything within that cone must make a DC 20 Strength saving throw or be sucked into it's cheeks Ybrik. While inside Ybricks cheeks, someone is under the effects of the stunned status condition. If Ybrick takes damage above 30 hit points from the outside, it will spit out anyone inside its cheeks.
