该剧以发明创造为主线，描写嘟嘟宝星球上的两位主要人物：发明狂卡卡嘟和他的随从波波嘟。卡卡嘟会发明任何特别神奇、充满智慧和想象力的东西，但这个东西一旦到了波波嘟手里，总会产生意想不到 的效果，反而让发明者卡卡嘟处境尴尬或狼狈。波波嘟看起来傻乎乎的，但其实他常常是大智若愚的；而卡卡嘟看起来极其聪明，但其实常常又是漏洞百出、弄巧成 拙的。这两个人物本身就是一对矛盾，使故事充满了诙谐和幽默，极富逻辑性和想象力，给人以启迪。

Well, here it is everybody, the final season of "My Little Pony: Friendship Is Magic", one of the most popular things that we as humans have ever created. Here we get to see a new villain called Grogar summon the other My Little Pony villains. We get King Sombra, Queen Chrysalis, Tirek, and Cozy Heart gathered together. What's great is that everybody stays in character. King Sombra wants to go back and conquer the Crystal Empire on his own. He actually does seem to do that! I just love how fast paced everything is in this episode! There's also the other plot about Princess Celestia and Princess Luna giving up their ruling title to Twilight and her friends. I would like to see if they inherit their powers too. The animation is probably the best it's ever been at. Only appropriate for the final season. Thanks for the memories!
