A toy is an object that by either owning or playing with one brings joy to an animal or person, usually a child. There are toys however that are considered "adult" which are expensive, grandious, elaborate, or extremely functional and elicit a feeling of desire. A corvette is often referred to as a "toy" in the grown-up world, whereas a rattle would be a toy for a baby. Humans also buy toys for their pets: for cats, animals stuffed with catnip; for dogs, a rubber bone or a facsimilie of a real-world item that is designed to "squeak".
Toys are usually designed with purpose and gender in mind. Models of cars, trucks, weapons, and other "flashy" and functional toys are often marketed toward boys, while dolls, home appliance simulations, "beauty kits", design and decoration kits, are marketed toward girls. However this distinction while having commercial implication, may not be made in all households. Parents may choose to raise their children to pursue their interests and not assign gender designations to toy selections.
Some toys, such as puzzles and games, are marketed independant of gender, although frequenly in advertisements boys are depicted playing them.
Some toys are manufactured in conjuction with movies, cartoons, or television shows and thus have an implied "value" associated with them. In these markets some toys are only in manufacture for a short period of time, and the popularity of the toys results in increased demand. This places them in a "collector" status, and may be more valuable in the future depending on certain conditions such as packaging, integrity, and appearance.
Not all collectable toys are made in association with promotions. Some toys are produced with error, which increases their value due to the limited production with that error; such mistakes are sometimes corrected in future productions.
