There is a tree house at the back on the right side in Wildwood Glen, you need a Grappling Hook and Rope to enter it.
When you have that item, click on the Tree House and play a long game of Jumper (where you have to take all honeycombs and avoid beehives).
In the tree house lives Spy Bear and he sells spy items (only one item per day):
- Spy Gear (Recon Goggles, Dark Moon Specs, Super Shades and Spy Briefcase)
- Spy Clothes (Stealth Gear Top and Stealth Gear Bottom)
- Spy Home Stuff (Spy Central Communicator, Spy Database Processor, Spy Data Configuration Unit and Spy Bunker Door)
