The sleeping ghost crew holds a bottle of grog.
But he pulls it in too quickly for Guybrush to grab it.
You have to make him drop the bottle.
Which of the ghost's body parts is sticking precariously out from under the blanket?
His feet.
Now, what do you know about feet?
They tend to be stinky, sensitive, and...
Ticklish.
You need to tickle him.
But you can't do this with your bare hands.
What implement do people often use to tickle others?
A feather.
Where can I get a feather?
Now, tickle the ghost's feet.
Standing by his feet, use the feather with the sleeping ghost crew.
He flinched, but he still didn't drop the bottle.
If at first you don't succeed...
Try, try again.
Tickle him repeatedly until he drops the bottle.
Now pick up the jug o' grog.
