Stuffed Animals
You can never go wrong with a stuffed animal guinea pig. They range from the traditional cotton-stuffed variety, like the cute ones by Douglas stuffed animals, to plush puppets to battery-operated, motion-oriented guinea pigs, like Hasbro's FurReal Friends. These stuffed animals are appropriate for kids of all ages, and range in size from miniature to larger-than-life.
Action Figurines
There are a number of plastic guinea pig figurines for both boys and girls. Playmobil makes several sets specifically dedicated to guinea pigs. One includes a cage and food for the family of eight little critters. Other companies manufacture animal sets that include guinea pigs in the mix along with dogs, cats and other popular pets. One popular set are Jumbo Pets, available through many online toy retailers. Check if the figurines are age appropriate for your little one, as many of them have small parts.
Video Games
A number of action-packed video games, especially those affiliated with the "G-Force" film, have hit the market since 2009. The G-Force video game is available on all of the major game platforms and loosely follows the film's narrative, according to a USA Today video game review. A number of free video games featuring guinea pigs are also available online for children of all ages at sites such as Guineapigsclub.com and Petgames.my-pet-care.com.
