UltraBaaBaa is the Starred Alien variant of Baa Baa. It first appears in the 46th Stories of Legend sub-chapter, Singularityville, which was added in version 6.9
Has an acceptable amount of damage per hit, but its attacks are single-target.
Has even less health, but more importantly, it has a barrier with a whopping 266,000 health! To break it practically, cheap Barrier Breakers or extremely strong Anti-Aliens are needed. Its barrier has a health of a very highly magnified One Horn, that can tank even the highest damage of Uber Rares.
Dictionary
English Version
Stellar sheep with mighty barrier defense. Spiky looks are actually just bad bedhead. Since everyone keeps their distance, she's paranoid about her breath.
Japanese Version

translation
堅いバリアを身にまとった宇宙の羊。
体のトゲが特徴的だが実は寝癖。
本当は柔らかボディなのに近寄りがたい
見た目なのがコンプレックス。
A sheep in the universe wearing a hard barrier.
Although the body thorns are distinctive, it is actually a sleeping habit. It is a complex that looks like it's hard to get close to being a soft body.
Strategy
This enemy is similar to Celeboodle, just with 3,000 more damage. One can be easily stalled using a couple of meatshields, but many of them at a time could be deadly.
Her insanely strong barrier is basically her lifeline--once you destroy it you can kill the unit using even the weakest of cats. The question is, how does one destroy the barrier?
Firstly, you must notice that even Bahamut Cat is far from being able to destroy it, you need insanely strong hits to destroy it (like a level 37 Hallowindy). Of course, you can just use Barrier Breakers such as Fencer Cat.
If you don't have a Barrier Breaker or a very highly-damaging cat in your lineup when you meet this unit, UltraBaaBaa is quite literally undefeatable.
A level 33 Lufalan Pasalan can break an UltraBaaBaa's barrier with a critical hit, though this method is NOT practical or recommended
A level 50 catman with all anti-alien treasures will always break UltraBaabaa's barrier.
