Abstract: A cap assembly for containers includes a body, an exit aperture and a closure mechanism. Externally, the body may be shaped and designed to provide fun and entertainment value. The aperture is in fluid communication with the container to enable contents to exit the assembly. A closure mechanism closes the aperture and facilitates storage. The cap assembly includes a connector portion configured to be coupled to the container. The connector portion may be configured to be removably coupled to different containers having different spout configurations.
