They must be very precise creatures. Here's a gem from the bottom of the page:
"eat a larch tree bark
bite off a twig at 10 cm point from the tip
drop a brown old bud, eat only the bark skillfully
leave the white core like a needle"
It's almost haiku!
From the Atelier Momonga homepage:
"It is also claimed to be the true identity of the TENGU (long-nosed goblins)said to live in the mountains." MYSTERIOUS.

He's training a momonga to do his bidding!
(Also: if you mouse over the momonga on the index page, it will fly around. Just thought you should know.)
