So I decided to shrine my collection of Tecmo soundtracks (small as it is), and found:
Angel Eyes ST - locked
MF1 ST - Zuum/? (Dino, just like the MF1 game)
MF2 ST - Ripper/? (Nightseeker*)
MF2 ST Bonus disc - locked (makes Gold Suezo in MF2)

* This ripper is really weird. It won't 'stick' in my Encyclopedia. It's shades of blue, but has absolutely no form or texture. It's not even 3D. It's as if a hole were cut out of the game background wherever it stands, and you just see some blue colors.

When you combine two monsters to get a new monster (not already in your encyclopedia), it adds it, right? Maybe if you get another one, and combine them, it will 'stick'. Then again, maybe not. ^_^

That Ripper may look cool in the adventures.

I checked my Encyclopedia at the ranch, and the Ripper is in it. I don't know what happened. I do know that I originally shrined it, rejected it and kept shrining CDs. Then my husband came into the room, and I wanted to show it to him, and it wasn't in the Encyclopedia. I only had one Ripper (Ripper/Tiger)in it -that I had shrined long ago and never raised.

It also does carry over in combination, just like Dino does.

Thats crazy, and sounds like a very cool monster to me. Can't wait to at least try and raise one...try.
