Episode Summary


Experiments 501 and 502: YIN & YANG

Experiments 501 and 502 are both activated, two experiments that aren't supposed to come in contact. Unfortunately, Lilo and Stitch are having some problems with each other, and soon decide to split apart, with Lilo teaming up with Pleakley, and Stitch teaming up with Jumba. Can they make-up, catch the experiments, and learn about yin & yang in time before the experiments come in contact?

  • Experiments 501, and 502 are the mentioned evil experiments

    When two experiments activate at the same time, arguing Lilo and Stitch insist they each can catch an experiment without the other. Meanwhile, Jumba and Pleakley make a bet to see which one will capture their experiment first, and Gantu forces 625 to help him catch them both. The race is on, because if Jumba's theory is correct and the two elementally opposing experiments touch, the world will be doomed. This theory is proven wrong because lava, is a form of melted rock, and when cooled down, condenses it, causing it to turn into lava rock, thus together they make an island.moreless

    actually i didn't watch yin and yang's doesn't showing their episode...i had watched it but at the end only..i think this episode of yin and yang was very cool,wasn't it? i like their powers to control fire and water as their one true place is with them...i actually wanted to watch yin and yang's episode!!! i hoped one day if i opened the tv and decided to watch lilo and stitch....its yin and yang's episode..moreless
  • Absolutely great I am telling you! Opposite but they may have made a little error!

    Absolutely great I am telling you! Opposite but they may have made a little error! If you would look carefully the first experiment pod that was activated was Yang and the number of the pod was 501 and so as Yin the number is 502 well later on Jumba said that 501 is a water sprinkler and 502 has something to do with pyro! Well even though if they made errors it is still a beautiful shot well done at least it is not just safe!!!moreless
  • Teamwork, always work together!

    This episode was just awesome! Perfect episode to teach a lesson on teamwork. Everyone may have been seperated at first, but they make up and work together. Lilo and Stitch, for example, always argue but never split apart from each other. They are two peas in a pod. The dynamic duo. Brains and brawls. Jumba and Pleakley always fight too. They make up silly thing to argue about. But they never really leave each other behind. Teamwork creates caring for someone else. This was the main lesson I understood here in this eppy.

    Another thing about this eppy is the cool experiments! Yin and Yang are awesome. For a lava spewer and a water sprayer, they are one of the most collest experiments I've seen so far on the series. I mean, lava may be destructive, but combined with water, it creates a wonderful thing. Plus, they have strong powers. Lava contains heat, and fire. Water contains pressure and rapid speeds.

    Bottom line is, this eppy is one of the greatest. The yin and yang concept really fits here. Working together, you can achieve great things. And powers aren't the only power. The power of teamwork is infinite. That's why this eppy was so good. It teaches a good lesson.moreless
  • I thought Lilo & Stitch were better friends than this.

    Lilo & Stitch are supposed to be better friends by now! Other than that this was a pretty good ep, liked the Glocknar dance. It\'s always good when Jumba and Pleakley argue. And the chasing was fun. And the 625/Gantu interactions are great in this ep. But shouldn\'t Lilo know better?

    • B: Miscellaneous Notes

      --> Donuts & Mustard? Yuck. What a disgusting combination

      --> Since L&S both caught each experiment, J&P's bet ends in a tie. BUT ... according to INTERGALACTIC WAGER RULES, in the event of a tie both parties must pay the bet. They both lose and have to do the dance.

      --> After overhearing Gantu & 625 argue about teamwork, Lilo & Stitch make up and go after 501 & 502 together.

      --> Jumba preps Stitch to catch 502. While Pleakey preps Lilo to catch 501. Yin is a female and Yang is a male.

      --> The Funky Glocknar dance of 1000 hours. They never mention if it is 1000 Earth hours, or 1000 Glocknar hours, or 1000 hours on whatever planet you happen to be on. On Glocknar 1000 hours might be a lot longer or could be a lot shorter.

      --> Jumba & Pleakley make a bet. Jumba thinks Stitch will win, Pleakley thinks Lilo will win. But ... according to INTERGALACTIC WAGER RULES each bet must have a price. They decide that the loser has to perform the dreaded glocknar ceremonial dance known as the Funky Glocknar. The witless dance of 1000 hours.

      --> Lilo and Stitch do a lot of arguing at the beginning of this episode and decide to split up. Each will take one experiment and see who catches their's first.

      --> Gantu makes 625 help him, but 625 thinks they could work better if they each track down one experiment.

      --> In this episode, we learn all the experiments in the 500's are elementals.

    • Dance the Funky Glocknar Four Eyes

      This is an allusion to the song "Play That Funky Music White Boy".

    • Escape From Witch Mountain

      625 is reading the book "Escape from Sandwich Mountain"
      The title to the book is a play on the novel, Escape from Witch Mountain. Disney created a movie with the same name and based on the novel.

    • Animaniacs

      Lilo constant "Why?" sounds a lot like Mindy from the classic Mindy and Buttons segments of Animaniacs. Mindy, the little girl, was infamous for asking "Why? ... Why? .... Why?... [etc.] Okay, I love you, bye-bye!" whenever she met someone new.
