Any bosses i've missed other than cthulu?

[Fitsu]

Hey guys, joined here about a week ago.. Wondering if there's any bosses I've missed? Other than Cthulu, can't get those damn puzzle boxes to drop... Bosses I've killed -

All 4 Dreamland bosses
Time Rift Diablo/SK/Butcher
Lich King
World Stone Event (inc belial)
Ctoggha (thanks for the tip about item find barb to get puzzle box )
Trag-Oul
Crucible 1 - 20 (inc tyreal, thanks for tips on this to guys felt impossible at first ^^)
Ubers inc Uber Diablo
Inferno Cows & the zone prior forget it's name
Icy Cellar place, that kind of had a boss in it? I guess fire golems are like immune to fire as he did no dmg x)
Azmodan (I actually left this guy to last as he was the newest I was expecting him to be the hardest, was kinda dissapointed as he was by far the easiest boss of all the new bosses)

Kinda surprised I seem to have managed to kill everything, considering I have yet to even put 1 enchant on my gear, hell I've yet to even hit 95 for my prime/belial charm yet XD... I imagine in top-end gear this stuff must be incredibly easy to do.
