To play in the Woodland Wonders area of Webkinz World, you must have entered at least one figure code. The Woodland Wonders section is located in the Magical Forest from the main menu.

There are 48 figures to collect/win in the game. Once you win them, they appear in the Woodland Wonders Collection page. 15 of them are 'common', 21 of them are 'uncommon', and 12 of them are 'rare'. From the Wonder Collection page, you can drag up to 2 figures to join your pet icon... this is very similiar to how the charms work.

You can also collect/win keys in the game. There are 5 rare emerald keys, 10 gold uncommon keys, and 15 silver common keys. When you collect all the keys of a color, you unlock the door and get to pick a prize. Note that many of the prizes listed can only be won this way.
