When everypony/body got to Ghastly Gorge Scrooge toke out the map and give it to Twilight so she can translate it.
"First we go to a rock that looks like a wooded leg" said Twilight.
"It's over there." said Dewey and he pointed at a rock that was five feet away.
"Good job lad." said Scrooge
"Next we need to find a cave that's near here." said Twilight.
And they found a cave next to them.
"Then we go inside the cave and look for a x near a tunnel" said Twilight
Scrooge turned on is flash light and twilight used magic to light up the cave and whet inside the cave. they fallowed the tunnel untell they came to a fork in the tunnel. There whir three tunnels but, all the tunnels looked the same.
"What do we do now?" asked Scootaloo
"I think I got it, can I see the flash light Uncle Scrooge?" asked Huey
Scrooge gave Huey the flash light and shined it on a odd looking stalactite. the stalactite made a x like shadow near the left tunnel.
"Just as I thought" said Huey
"Way to go laddie" said Scrooge
Then they came into a room with different tiles on the floor (in a 5X5 grid) and there's was sign that read:
----------------------------------------------------------------------------------------------------------------------------------
To whom it may be. To find me Treasure you need to spell me name.
-PG
----------------------------------------------------------------------------------------------------------------------------------
they looked at the tiles and noted that each tile had a letter of a strange alphabet.
Twilight toke out a piece of paper and quill and wrote something on it. Then she gave it to Scrooge and told him that's Peg-leg's name in this alphabet. Scrooge jumped tile to tile untell he got to the other side. then everyone/pony did the same. in the next room they found Peg-leg's Treasure.
"Bless me Bag pipes we did it." said Scrooge
Then Everyone/pony garbed some treasure and left most of it to anypony who can find it. (namely Daring Do) Then they somehow they triggered a trap and a large bolder rolled to them.
"Run!" said Filthy Rich
They ran as fast as they could untell they got out of the cave. Then everyone/pony whet home.
I know action scenes are a pain to write, but if you skimp on the description with them, they're not going to draw your readers into the story.
