Key, New Room(s)!!

Hello penguins!
The key is at the Book room and you go on RH journal, go to the last page and click the picture like this below.
To get to the Crow's nest click the arrow.

Here is an image of the Crows nest.
Here is RH's Headquater's, you don't need the key to get but I'll suggest that you get the key because then you can go in the Headquaters every time the captain comes.
Until then...waddle on!
