Climb into the net, take a good look around with the binoculars, look for something red
There are two birdhouses with a lock. Make sure you open both with the keys in your bag.
When you are in the climbing net you can read four symbols on two red bird houses. You can look up these symbols in the two bird houses with the lock. The symbols correspond with letter that will form a name. You must fill it in.
