An additional Shibalien is spawned when the enemy base falls below 90% HP, but does not cause a boss shockwave.
Plays out similarly to the previous Chapters, but many, many Shibaliens spawn when the enemy base is attacked instead of just one, along with a fake boss in the form of Squire Rel.
Tested strategy in Chapter 1
Spam Giraffe Cats (level 20+0, 300% Treasures) and deploy a Valkyrie Cat (level 20, 300% treasures). Even though the Giraffes can clear this stage easily, Valkyrie Cat can destroy the base in one hit (save time).
