Kids content includes cartoons like Pokemon (sorry, but it is a cartoon; they are not real), SpongeBob Squarepants and more, all delivered ad-free. Of course, there is the $7.99 monthly cost of the service which allows you to watch with limited commercial interruptions. If you don't want to be interrupted by any ads, the service will cost you $11.99 a month.
If you have a Windows 10 phone, tablet or PC, you can install the Universal Hulu app by clicking on the sourcelink. One the app is installed, you can subscribe to the service. After all, who wants to miss SpongeBob and Patrick getting into their latest mess.
