7-4 and 7-5
It makes sense to many fans to do level 7-5 before level 7-4 because 7-5 blocks a Toad's House with a Frog Suit that is useful for 7-4. Why, then, are the 2 levels numbered as such and not the other way around?? Koopa lover 15:14, 10 April 2007 (EDT)
Yes, each of the three main islands makes a pipe.
