Yes there is, i know for a fact that moltrasis at the top of mt blaze. i think there is around 15 floors then a save point then theres 5 more.
Zapdos in mt thunder Articuno in frosty forest Moltres in mt blaze
I believe the top floor off mt blaze is floor13
you do whatever you want, you can go back and recruit the legendary birds,(mt thunder, mt. blaze, and frosty forest) get the legendary dogs,( i forgot it's like someodd fieldsfor all three) or get Hoho(requires rainbow wing, you get parts of it from the legendary dogs)
Zapdos is in Mt. Thunder Peak. Moltres is in Mt. Blaze Peak. Articuno is in Frosty Grotto. To meet them again and recruit them, pass Mt. Thunder, Mt. Blaze, and Mt. Freeze without doing any rescue missions.

Before everything you must make in Mission objective the word "fugitive" to write. Before you can go to the Mt. Freeze, there are three levels: Lapis cave, Mt. Blaze and Frosty Forest. At the Lapis cave there is no boss, but at the Mt. Blaze and Frosty Forest are two legendary birds that are tough to beat( these are moltres and articuno, zapdos is already met before). As you see, there is only a little number of these levels, but they are full of powerful enemies and have lots of floors so it won't be "a piece of cake". Good luck! ;)
moultres you are welcome
at the end of mt. blaze is a Moltress. if you're grass or normal type, you might want to bring some blast seeds and gravel rocks.
