The 2nd Dimension (not to be confused as the other 2nd Dimension from the UnAnything Wiki) 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.
MOAR! Info Edit
In the beginning, Danville of the 2nd Dimension is ruled by 2nd Dimension Doofenshmirtz and his family (Charlene-2 and Vanessa-2),
However, Doofenshmirtz-2 and Charlene-2 became divorced, and all of the animal agents (including Perry-2) got captured and turned into ruthless cyborgs. There is a group called the Resistance founded by 2nd Dimension Candace sometimes.
This is where the Phineas and Ferb cartoon happens. There are few moments where another dimension is seen or mentioned, most notable is in Phineas and Ferb The Movie: Across the 2nd Dimension. The only observable difference between it and the second dimension is that in the first dimension First dimension Doofenshmirtz never lost Choo-Choo, that making him less evil, so that he never took over the Tri-State Area. But now that 2nd dimension Doofenshmirtz found Choo-Choo and lost his "true evil", these two dimensions could be almost the same again. But in 2015, The 2nd Dimension's existence started to get berserk, haywire, retarded, and horribly wrong. Now became a famous place for video game bootlegs
