why did all the other bosses burst and died, but dodongo didnt die and just sank in the lava. why didnt he burst?
Well not all "burst", some disintegrated, but I think that's really just making use of the lava. And that's a really cool and painful death you gotta admit that. Although, now that I think about it, the one death of a boss that you have blow up bombs in their stomach and they don't explode? That is strange.
