I refought Cackletta last night, and I haven't a clue in the world what attack you guys are talking about.
The eye laser one where you're supposed to be in the air if she looks down, or on the ground if she looks up?
The sphere one where she randomly flashes an assortment of purple, red, and green spheres, then when it teleports away, a red one attacks Mario and a green one will attack Luigi, and if you manage to miss it with your hammer it does 2 HP damage?
(Granted, I could be a bit overleveled, but my Bros. only have about 110 HP each, which kind of freaks me out when there's a mushroom to restore 120 HP, then another one to restore "all" HP. Though I am the type who'd rather boost Defense than HP.)

Where are these lemmings going? The
Super Nintendo Super Shire! Hop in line and follow them there!
