I am new to Subeta. I recently visited the Glade and happened to have an empty bottle I could fill. I then noticed that the filled bottle has a special use option. What does it do? I don't want to waste it.

If it's just a regular water bottle and you use it on your pet it will transform them into an experiment 7463

If you have an Ornate Floral Pitcher you can fill it from the Subeta hours

8am - 9am 8pm - 9pm

and then if you use that it will transform your pet into a glade pet.

That's really interesting. Thank you for answering me. The bottle I have is a Filled Pyramidal Bottle. I'm glad I didn't use it before figuring out what it does.

You're welcome! I know what you mean, I would be pretty shocked to find my pet transforming without knowing what I had done.
