The 2nd Dimension from the Phineas and Ferb multiverse (a.k.a. Heroic Candace's universe) is the most infamous and less popular dimension ever discovered, In 2015, it became part of the Un-Multiverse and a source of Youtube Poops/ YTP. This dimension is now became infamous, less popular and least favorite and also as a place where Dan Povenmire and Jeff "Swampy" Marsh hid their 2nd Dimension stuff and used it only as a Phineas and Ferb movie and an story arc episode and abandoned it after they make an series finale and a stand-alone episode of Phineas and Ferb.
