    I have got a theory that in symbionic titan that guy who repaired octus in the final episode was Lance's lost father, only someone well educated from Galaluna could have pulled this off

    If they think these are the most jaw dropping, wait till TADC episode 7 comes out with a plot twist!

    For the record, I don’t know anything about the episode as much as anyone, all we know that it’s a beach episode, (or at least that’s what it seems) but I heard the creator attempts to make the biggest plot twist possible! We’ll have to wait and see on Dec 12th!

    52:20 people guessed this when season one was out. It was a theory based on the French revolution, where royals who were for the people gave up their royal identities to become the leaders of the common people with insider knowledge.

    Hmm I think you forgot about the other plot twist for the Venture Bros, it's in the Movie… Spoiler Warning, it's where they find out that Rusty Venture and the Monarch are actually the clones of Dr. Venture aka Rusty's Dad but the Monarch has Baboon DNA mixed in his where Rusty doesn't, so pretty much Rusty and the Monarch are sibling's just one with more altered DNA it's why the Monarch is so aggressive towards Rusty due to instinct.

    Top 10 request: Top 10 other children's cartoons that have reached the same amount of popularity as SpongeBob SquarePants.

    Rules:
    1.) The cartoons featured have had to run alongside SpongeBob for them to be able to compete with the show in ratings/popularity overall.
    2.) The list won't feature any preschool shows or adult sitcoms as they are completely different demographics from SpongeBob's, only TY-7 & TV-PG rated cartoons will be featured.

    Suggestions:

    The Powerpuff Girls (original series), Kim Possible, Ed, Edd n Eddy, The Amazing World of Gumball, Big City Greens, Adventure Time, The Loud House, The Fairly OddParents, & Phineas and Ferb.

    I don't like Ed, Edd, and Eddy, but HOW is Eddy's brother a plot twist? Am I the only one who saw how genuinely terrified and unnaturally subservient Eddy was when Sarah and Jimmy made him think his brother had come home?
