Big Bowser (unused sprite) (62, rev. 18)
By  Hiccup on 07-29-16, 08:58 am
Category 'Bosses and cutscenes', known
Spawned out of pot in final boss.

Game crashes after roaring animation if used anywhere other than World 8 Final Castle Area 3.

The fireballs seem to crash the level. It is possible that a sprite set needs to be selected in order to use this sprite.
