Does it give a little extra to stats? if so to what and how many?

Is this the item you're talking about? I don't think it's anything other than food. Usually if there's more to it SubetaLodge would have it listed under notes. For example with Clear Slime there's a note saying "Stat Booster: 0 or 1 Level".

Yes! I looked in SL, it just seems odd that it's 400k+ for just being food. Oh, congrats on having that many fake rainbow star rods :) Lol, your username actually reminds me of a pet I used to have with the same name :)

The Magical Mushroom is a R99 food and there's two achievements which require feeding your pet R99 food(s). One having tiers up to 25 different foods. There's only 40 R99 foods total.

I ❤️ my Fake Rainbow Star Rods. I don't play Slots enough these days though to constantly add to my collection.

Ahhh! I see now, thanks:)
