Rare Items

[Poltin]

I thought it might be useful for to have a list of all the rare items in the game for those who like to gather such things.

If/when new rare items get added, just send me a message or leave a post here. Preferably with a screenshot.
Or, if you know how the item is awarded and I don't, tell me as well.
I'll be updating this post as it needs to be.

The List
Silly Party Hat-Awarded for joining Cozy Quest on the first day
Pelitucana-Unknown
Pimposius Hat-Unknown

I believe that the two other items on the list are personal gifts from Nils for some reason.

The Cozybase will have a Reward tag for items, which fall under this category. ^ ^
