Motley Bossblob has picked up a mean trick since your last encounter with him: harmful shock waves emit from where he lands after any jump. These shock waves expand fairly slow, which makes them a longer-lasting threat, and they also have pretty good range. Additionally, he starts off a lot faster than he ever was in the first encounter, and he only gets faster. Every time he gets hit outside of his massive Motley Bossblob form, he adds more jumps to the first half of his routine, which means large portions of the arena are danger zones constantly.
Still, despite these enhancements, Motley Bossblob still follows roughly the same patterns and tactics as before. After three hits, the boss is defeated and you’re awarded a Green Star. You still need to reach the top of a Goal Pole before this level is completed.
