Adventure Time

Adventure Times first episode was in August 5.2010 and their final episode was in September 3,2018. Twelve- year-old Finn battles evil in the Land of Ooo. Assisted by his magical dog, Jake, Finn roams the Land of Ooo righting wrongs and battling evil.

Usually that evil comes in the form of the Ice King, who is in search of a wife. He's decided he should wed Princess Bubblegum, though she doesn't want to marry him. Still, he persists in trying to steal her away, and Finn and Jake, along with Lady Raincorn (a cross between a unicorn and a rainbow) do their best to keep her from harm.

This show is on Cartoon Network and it is created by  Pendleton Ward. I was never into this show but a lot of children that I saw like this show.
