Worms: Phineas & Ferb Edition is a fan fiction game concept by WikiaIvan1997. It uses the Worms: Reloaded engine. It also includes a unique Challenge Mode, based on every big idea that the boys made from seasons 1, 2 & 3.
The story involves Phineas, Ferb & the gang building Wormsland, a theme park dedicated to the Worms franchise. They invite everyone in Danville, including Candace, who thinks her brothers are up to no good again. Meanwhile, because L.O.V.E.M.U.F.F.I.N. isn't invited to Wormsland, Dr.Doofenshmirtz builds a Wormsinator, which can turn anyone, including animals, into a cartoony worm. L.O.V.E.M.U.F.F.I.N. shoot at Wormsland, turning everyone into a worm. Perry is turned into a worm too, and is teleported to Wormsland. It's up to Phineas, Ferb & everyone else to get to L.O.V.E.M.U.F.F.I.N. and put an end to their evil scheme.
The worm customization is just like Worms: Reloaded, but with a twist:Each worm in the team will have their own seperate soundbank and clothes. The soundbank editor is improved, with all of the soundbanks from that game, plus a few from Worms: Ultimate Mayhem. The soundbank editor allows the wave files & MP3 files to be used, and they can be as long as the player wants. There are also several Phineas & Ferb soundbanks.
