Last time when our party encountered a gelatinous cube, we wondered how they reproduce. We instinctively agreed that they reproduce like amoeba - by mitosis or cell division.
However, I'm curious:
Is there a canonical D&D reference to how gelatinous cubes reproduce?
I'm very interested if there is a reference in an early D&D edition, and especially more interested if there are different methods proposed between editions, if any. Answers from Pathfinder are also welcome, since they stem from D&D, too.
