Tale of Diep:Cascade Army

This is just a concept idea for a new boss in diep.io. Such enemy doesn't exist. (Maybe) If the tanks keep ''destroying them, a storm of them will occur; one by one they unite and full of determination to dominate this arena. They hear the cries of help from the three-sided figures, and this is their wish granted.''

Overview
The Cascade Army is a mass swarm of Cascade nest defenders, they only spawn after the 20 Triangle nest defenders have been destroyed in the server. Unlike other polygon bosses, the Cascade Army is technically not a single bodied enemy. Instead it's a collective swarm of Cascades cooperating and smiting their enemies. This the boss version of Swarm Seekers.

There are two different phases for this boss, phase two activates only when three Cascades are left.
