Locations of Rare Monsters in RF4 and Rare Items

Nowadays, there are plenty of Guides on the internet that list all the Monsters and all War Trophies perhaps, but I still feel it may be useful to give a few tips about the locations of some of the rare Monsters and some of the rare War Trophies and items:

There are four elementals of different colours, simply given the name of their colours.  They make wonderful allies but it can be difficult to find them.  They only appear rarely in their designated locations, so if you really are determined, you should save, then go on and off the screen until one appears.

Green:  When you first explore Idra Cave, you will have an opportunity to accept a little Green into your Party if you have a Monster Barn with a free slot.  After that, you can find them in the little screen with the pond in the Maya Road area.

Blue:  South of Cave in Sechs Territory
Red:  On Autumn Road on the screen east of the Revival Cave
Yellow:  Sercerezo Hill on the screen with five stumps west of Idra Cave.

The following are Monsters that occasionally drop a very rare item:

Pink Dragon: rune Prana 6: Love Sclae
Yellow Dragon: Rune Prana 6: Glitter Scale
Golem: Floating Empire, Golem Stone
Guardian Rune Prana 6: Golem Spirit Stone
