you have to talk to the porter and she will tear the orders out. then you have to use the pencil to rub on the tablet and that's where you use the pencil.
Hope this helps! :D
you use the pencil
A Cabin
In order to reveal the notebook passage on Mystery Train Island, find the pencil.
You use the pencil to shade out the words.
You find a pencil when you enter the train. When you visit Tesla after his arrest, give him the pencil to draw a sketch of the room. Use it to circle the missing briefcase -- you can only do this if you have visited his cabin already.
You just go to the place you got it.
you click the pencil once then you circle the briefcase.
you need to first find a pencil but i cant remember where to get it.. its somewhere on the train and when you get the notepad go into you inventory and click on the pencil. the it will come up with the notepad and pencil and all you have to do is draw over the notepad until it stops you
Get off the train thean get back on. you will be at the front of the train when you do get back on. go to the coal room to the left and talk to tesla. give him the pencil to use. go to teslas cabin. thats as far as i got.
Well, that really depends. If you mean on mystery train island, then the pencil there is on the ground, near the table in Eddisons' car. Good Luck, I wish you the best. :-)
She throws the paper away. After she does this, find the pencil/crayon whatever it is, and say 'use' next to the notepad. The imprint will tell you what you need to know.
you probably picked up a pencil earlier in the game click use it in your items, if not its probably on the ground to the right in one of the passenger cars
