MitD III: You are likely to suggest Tarrasque

[mastermind]

A bit off-topic from the current conversation, but...

I realize that the line between something I made up and something someone else made up is a pretty fine one, but I trust that someone will figure it out eventually.

I think it might be from dungeonscape (I'm probably wrong, because I haven't actually looked at anything from it. But I still think this part is important)

Or, perhaps, from Monster Manual 3?



Or am I just repeating someone else?
