The forest was odd, but it was hard to put a finger on why.  Something about how the trees moved... not very much like how they should, given the wind...

"Anyone else sensing something weird?" Alicia asked as they jogged.

"It is a little creepy in here," said Luisa.  "...something weird about those trees."

Alicia tossed a flower blade at one of the trees.

It stuck in the tree.

Alicia went to retrieve it, staying on guard.

It took more tugging than was really right to retrieve it, and a long strand of greenish liquid followed the blade out of the tree.

"Uh, this is really weird," Alicia said.

"That's really strange-looking sap," said Luisa.  "Is that normal?  I don't think it's normal."

"It's not normal at all," Alicia said. "I have no idea what's causing it."

"Well, for now, let's keep moving," Rosa suggested.  "There's no point in starting a fight with a tree."

"You're right, but let's keep an eye out," Alicia said.

They moved on...

Perception

...the way the brush was moving was very much like something was moving behind the plants.  But she could see nothing at all.

"We're not alone. There's something here," Alicia said.

"Sounds like a good reason to get going faster," said Rosa.  "Come on, now!  Double-time!"

Alicia hurried up.

Athletics check

(OOC: Athletics check - Alicia Green rolled 16 using 1d20-1)

Something was definitely moving, and probably following them, but they were able to pull ahead of it and get away.

"I think we should let someone know about what's going on," Alicia said.

"...assuming that they don't know already," said Rosa.  "This might be a feature, not a bug."
