All Bobs Must Die:

The Black Forest was one of few forests left in the world that was still a place of strong magic. That's what Bunny had said at least and as soon as they started walking through, Kon was pretty sure why. It was misty and somewhat dark, like something out of a fairy tale. Very moody.

Which made sense, given the Brothers Grimm were from Germany. Kon half remembered something from English class about Little Red Riding Hood being inspired by the Black Forest.

What had brought them there was a critter roundup. Apparently both the Weisse Frauen - the white ladies, and the moss people of the forest had sent a message to the Guardians to ask for help. A strange beast was roaming the forest, one with glowing red eyes that moved in a flash of white and red. So far it'd restrained itself to only killing animals like wild boar for food but they were afraid it would soon turn its attention on the small sentient creatures of the forest since it seemed to be able to see them. Considering it'd also taken on a lynx or two and won they were afraid of what would happen if it turned its sights on them.

So there they were, going critter hunting, and if they removed the creature from the woods the moss people and white ladies, who'd taken a neutral stance against Kuk, would owe them a few favors. Which was definitely nothing to sneeze at. They desperately needed any edge against Kuk they could get.

"Be vewwy vewy quiet, we're hunting el chupacabra," Kon joked as he and Mikey crept through the brush, clutching a bag full of steaks in his hand. They were already nearly thawed. "It's probably not actually a chupacabra, though. Unless it missed a left turn at Albuquerque."
