Bouldergeist was the hardest part of it, along with the sand squizzard guy or whoever. Besides those it’s rather doable. Whatever the final level’s called -the one-hit version- was way harder
I don't think Squizzard was in Bozz Blitz..? If memory serves me right, BB only had Galaxy 1 bosses
But I agree, Grandmaster Galaxy with only 1 HP is hell
