Abnormal Beaver gets different move patterns, some of Yellow Beaver's attacks, and his forward-roll leaves explosions behind him.

Also, the special "purple flames" icon for Abnormal isn't used in-game anymore (at least, not for the lower HR ones). They got switched to the default icons for the species sometime while I wasn't playing.

Also, yeah, most of then are either minor or lazy changes, but Abnormal Conga was legitimately hard. Forgetting Cleansers pretty much means to forego healing for the fight, and he has a lot of HP and hits hard.
