I got one from the bath house today and my dumb butt accidentally fed it to my pet instead of using it I'm so mad at myself for making that mistake even if I still got an achievement for it 😑

I did the exact same thing, so I can definitely sympathize. Staff has started putting clarifications for feeding/using in item descriptions (like the gender/less berries), so maybe they can edit the description for the experimental dew, too--that'd be super nice lol.

Sorry to hear that! What achievement did you get?

Don't feel too bad I have done that myself. Wasn't paying attention... OTL

I got the 'fancy food' achievement. At least there was some good to this mistake

What does experimental dew actually do? I've just got it locked in my inventory 'cause I don't want to waste it. Last time I used something on one of my pets without knowing what it did, it turned into a pink horse.

It turns your pet into an experiment, which is a unique type of pet/colour that you can only get from experimental dew or the pet zapper
