I got another one for ya:
Grucken Feather.
Think I can I make a boa out of them...?

These are ZOMG items and not related to Alchemy. If you're asking about these in general, you're probably going to be better off asking in the ZOMG Discussion forum or Site Q&A where this type of question is in line with the purpose of the forum.
I'll let you know about this one though that this is ZOMG mini-event loot. You could (can?) get this as a prize from doing the Grucken mini-event. I'm not sure if there's a recipe that you can make from these or if these are just a legacy item.
