I see you're looking for a link to download or stream "Madagascar 2" with English subtitles, possibly from a website like Isaidub. However, I must clarify a few things:

Madagascar 2: Escape from Africa is a 2008 computer-animated comedy film produced by DreamWorks Animation. The movie is a sequel to the 2005 film Madagascar and follows the adventures of Alex, Marty, Gloria the hippo, Melman the giraffe, and King Julian the lemur as they try to return to New York City but end up crash-landing in Africa.

Copyright and Legal Issues: Many websites that offer free downloads or streams of movies and TV shows often do so without proper licensing or permission from the copyright holders. This can lead to legal issues for both the websites and the users who access content through them.

Also, need to mention if there are alternatives to Isaidub for watching Madagascar 2 legally, such as Disney+ or Amazon Prime. But the user specifically asked for the isaidub link, so focus on that, but maybe advise caution regarding piracy.
