It may be an insignificant bit of information, but if we're including "Volkner looks like Yondaime Hokage" as relevant trivia information, then this must not be completely nonsensical. I've had this happen on rare instances in the Underground--- when the computer which lays traps near sphere hotspots accidentally lays a trap underneath a merchant. The merchant will send out a white sparkle light on the touch screen and it is impossible to speak with the merchant without retrieving the trap he is standing on. (Unless you wait a while/ exit the Underground, then the trap may just disappear).
Mystery Dungeon traps?
I have yet to see any Crater traps in my game, although I don't usually peruse the trap merchants' stuff, so it's possible I've just never encountered one before. ---Spudwalt 20:46, 14 July 2011 (UTC)
