Ultra Stress! is the second stage in Monthly Events All-Stars Stages.
During the boss fight, more Chief Pengs and Firework Guys will be spawned as support/peons. Several Squire Rels also spawn, each one with a boss shockwave that knocks every cat back!
Beware the Shy boys, at 3-star difficulty they are stronger than the Shy Boys found in Unjust War!
Strategy 1 (cheese strat meant for farming)
At the beginning, spawn a Manic Lion Cat and a Maglev Cat. Maglev cat should kill the Chief Peng. Then spawn Awakened Bahamut and keep on spawning Manic Lion Cats. You should be able to destroy the base before Dark Emperor Santa spawns.
