At the hidden lake there is a barrel where the ladder is at the top.
It was only there in 2008.
Shake it up when you need it!
There are barrels outside the lighthouse and recycling center.

Go into the Lighthouse and go over to the penguin pushing the barrels, ask him for one, and put it in your inventory (If you can't get one, try clicking a barrel). DO NOT SHAKE IT YET!
It is in the book room in the coffee shop. It is a barrel, and it is on the table in the lower left corner.
