Alex, Marty, Gloria and Melman are still waiting the penguins
come back to rescue them at Africa
On the way home, they found out a travel circus,
they follow them and want to go back to their home- the New York zoo.
This time they have put in more 'well-known' musics,
and add in more characters which is from the circus.
If to compare with 1 and 2,
3 is not so good,
but somehow Madagascar is still one of my favorite cartoon :)
Hope there will be Madagascar 4
