"Super-Sized Darby" is the first segment of the thirteenth episode of My Friends Tigger & Pooh.
Rabbit has come up with what he believes to be his best invention yet - an Insta-Go-Grow potion for his precious plants. At first it doesn't seem to work, but when some ends up on Darby, soon she grows to the size of a giant. At first, Darby enjoys her new size and finding it helpful when it comes to Super Sleuth cases. However, it does have several drawbacks, including the fact that she can't wear her cap. Soon Darby finds herself less-than-enamored with her new height.
