Synopsis for "I Created Krang! Chapter One / Krang! Chapter Two"
A scientist comes up with a potion to increase the size of insects in order to put them to work for various industrial purposes. He is missing just one ingredient, sap from Krakow trees that grow only in Europe, but his fellow scientists think his plan is preposterous and he fails to secure funding to travel to Europe. Unwilling to give up, he makes the necessary financial sacrifices and, nearly penniless, makes his way by steamer to Europe thinking once he gains the sap and sells it he'll be wealthy. He approaches a castle wherein he will set up his experiments and is met by the caretaker, Ludwig. Ludwig assists in the experiments, but realizes he'll get nothing once the scientist sells the formula, so he decides to steal it himself, but first he'll make sure it works by testing it on an ant. Ludwig uses too much of the formula and the ant grows so large that its brain develops intelligence. At first it tries to get the scientist to hand over the formula so it can create an army to subjugate the world, but the scientist refuses and when Ludwig distracts Krang, the scientist escapes. Krang realizes that he no longer needs the scientist and so returns to the castle to recreate the formula by himself. Meanwhile, the scientist has used the last of his formula on an anteater which smashes into Krang's lab and finishes him off.
