"This is a fabulous Nintendo DS game, regardless of whether you are an online Club Penguin fan. The secret agent theme, delivered with a quirky sense of humor, makes completing the missions intriguing and hilarious. You can speak with penguins you meet, and if you help them with their problems, they will reward you with cool wardrobe additions or coins. The spy gadgets earned in the game, including a decoder and a two-way communicator, make the gameplay varied and interesting. Plus there are special Spy Puffles, little pet-like bundles of fur, who can help you in tricky situations. Another nice feature is a special Command Coach mode where a parent or older sibling can join in with a younger player to help them complete missions. By using two DS units connected wirelessly, the parent can serve as coach by circling areas to explore on his or her DS, and those hints then show up on the child's DS. It is a very clever addition to family gaming.
For fans of the website, this DS world is very similar in look and feel to what you find on the website. Favorite online Club Penguin games such as Cart Surfer, Jet Pack Adventure, and Ice Fishing are here. The familiar locations are also the here, but this world offers new expanded areas. However, you don't have to be a fan of the website to enjoy this game -- it stands on its own."
