Keller sends the nearest giant toppling to crash to the ground! 

The other giant turns and stumbles towards where it's fellow just fell, but it's head is still in the fog, and it swings its club wildly.

Keller once again tries to trim the nails on one hand with the small scissors. Sleight of hand: 12

“Ow”

”Ow ow ow”

Bryn holds his ribs and thinks two things: 1) He shouldn’t have remembered his shield spell. 2) He hopes they can take these giants down quickly before one of them pounds him again. He holds his arm out and squints at the giant he just teleported away from and casts

Ray of Frost Attack: 11 Damage: 7

Of hit, the target’s speed is reduced by 10 feet until the start of my next turn. 

Bryn then uses cunning action to move to the nearby building and hide.

Stealth: 20

(so which giant is still up? The one right in front of grandpa, or the other one) 

((It was by Grandpa, but it moved SW within the fogcloud.))

BB moves to the nearest giant and hacks at the back of it's legs.

 Attack: 26 Damage: 10

(If there is advantage for attacking a blind target:

Attack: 15 Damage: 7)

((Just enough! Feel free to put some flavor on it!))

The last of the giants in this area falls, and you have some amount of time to catch your breath and prepare for whatever you wish to do next. Your horses are quite spooked,  many of them having run back out the city entrance.

Keller gets his nails back to normal with the scissors, and perhaps the help of others. "I remember when fights weren't so weird."

He'll scout ahead to make sure there aren't any giants farther along...

Stealth: 28
Perception: 10

You get your nails under control.

This area seems to be clear for the moment, despite the ruckus you've caused, no other giants came to investigate. If the intell from the giants prisoners can be believed, you've got another half dozen somewhere in the city. 

Grandpa looks around and sees that we have come out without any casualties.  After which he walks upto Storm

"Come on Storm, we should make sure to get rid of the rest of the giants; you have seen that we can fight them. It shouldn't take us to much time either, and think about how happy the people would be for the giants to be gone. Also, I'm not sure the horses will be happy to continue with more giants in the area. Ill see if I can get them to calm down a bit, send someone to help whose horse hasn't run off, will you?"

Than grandpa sits on Black and pushes him to dash towards the horses, where he will try to calm the horses down, so they at least won't run off to far.

I expect an animal handling is needed: 10

Verne eavesdrops on Grandpa's plan and jumps to volunteer to Help, using his Speech of the Woods to try and calm the skittish horses.

((@Secretfool - reroll that check with Vernes Help))

Bolt joins Grandpa: "Storm, we could fight them. Or we could try asking them what they're even doing in this area. Usually they shouldn't be so far from their territory ((is that correct?!?)). Aaaand then we kill them. That's what I would like to do."

Bolt walks off, trying to find and calm her horse.

For advantage, with Verne's help: 13

(Amazing rolls....)

Grandpa takes off on bolt after the horses, but as skittish as they are, some of them don't recognize the metallic hound and gallop off to the west. It's unlikely you'll be able to round up all of the horses any time soon.

((Correct, they are outside of their normal home range.))

((Crap, sorry. The notifications have been messed up for me and I missed the 'finish him' request.))

BB straightens after the kill and looks inordinately pleased with himself now that he is a giant slayer!

"I'm up for more slaying! Sir."

He goes to collect his horse from where he left her.

She's not there. Seems she, along with the other horses, got pretty spooked. 

"Damnit, bloody horses, why can't everyone have a ride like me" Grandpa says more to himself than anyone else as he pets Black. After which he moves back to the rest with the announcement that all (or most? were any left?) horses ran away towards the west.

"Well dang it. Guess we'll have to stay and eliminate the giants."
