Polly needed a compass to navigate the forest - and it's our job to find one.

This is one of the more obscure puzzles; the first thing you'll need to find is a key for the arcade machine in Uncle Jedo's basement.

See the signpost quote for a hint to its location.

In the Taco Shack, surprisingly difficult to see on the checkered floor, is the key we're looking for near the arcade machine.

Use the key to get into the arcade machine's coin cabinet.

You've basically got an unlimited money cheat now - use it on every money-requiring machine in town!

The one outside of the Taco Shack should catch your eye - especially with the "one in three gets a surprise" line featuring on its advertising.

Use the coin-on-a-string on the machine three times to get the coveted toy compass.

Show the toy compass to Polly and (if you also gave her the map) she'll be ready to guide you to PPH3!

When you've given her both of the things she requested, meet her at the forest sign.

It's... locked. Never easy, is it?

These hints will get you on a path towards finding the key.
