Dust Bunnies - small magical creatures that inhabit dark places (dungeons, behind the chamberpot, under the bed, etc.). They survive by eating dirt. When they get too large, they split into two or more smaller bunnies. If struck, they explode into a cloud that causes all nearby to sneeze uncontrollably.
I've had also had Spitting Images, Roaring Acclaims, and even Rogue Waves (water elemental).
*Plotti McPlothoek:* grizzled old hook-handed (x2) pirate always willing to give the PCs quest-starting info for the cost of a drink. Strangely appears in every inn or tavern the adventurers happen to enter as if all part of a cosmic plan scribed by a very uncreative and time-pressed god.

"Holy sh*t. Wouldn't you know it. There's Plotti McPlothoek. Plotti you ol' seadog, what brings you here?"
"Yarr, me vessel was blown of course and I set in here for repairs."
"Blown of course. That's for sure. That's some hell of a course error that put you here... in the mountains."
"Well, err... the wind... umm... maps..."
