Maybe their giant, adorable eyes shoot lasers?

The group followed Raelin into the darkness of the Nykter caves, ready for anything - be it trap, armed guards, or some kind of insidious spell or an ambush.  Eventually, the caves were simply too small for Tribby to follow, so she cast whisper, a mystical walkie-talkie spell, which would allow her to hear and speak to the party despite the distance.

They could all feel the Nykter eyes all around them... waiting, watching...

One ran up to the group.  "Hi!" it said.

Manbearpig smiled.  "Hi there."

"Whatcha doin?"

"Oh... we're looking for the Shaman, actually."

"Oh!" the little Nykter smiled, and grabbed Manbearpig's hand.  "I know the way, fowow me!"

The group looked at each other and shrugged.  Thus far, criminal masterminds, they weren't.

"What's your name?"

"Oh, uh... Manbearpig..."

"Hehe, that's a funny name.  I'm Baco, I'm four!"

"That's great Baco.  So, how far is the Shaman?"

"Oh, not far.  I know the way, 'cause I'm four!"

"Awesome!"
