Read the old wooden sign at the parking space. It falls off.
I have a wooden plank
Now you just need something to stick the plank into the boat.
How do I stick the plank into the boat?
You would need some sticky substance. You are in a camp, by the fire, after all.
Tell me what sticky substance should I use
Find some marshmallows.
Go into the Dorms and look at the bottom right bunk pillow.
I have marshmallows
Now just melt them by the fire.
I need something to put them in, first
So, you would need some kind of a pot, right?
There's pots in the canteen. Take one from there.
I have a pot
Put the marshmallows into the pot and melt them with the fire. Then you can combine them to the wooden plank and the patch for the hole in the boat is ready.
