I'd like to change my pet to a nuclear aeanoid but I'm not sure how to do it. Can anyone help?

either get an Aeanoid Seed and grow it while keeping the pet you want to turn into Aeanoid active, or get Aeanoid Schematics from Yun Enterprises and make yourself a mechanical Aeanoid, or maybe Vanya will make you a Nostalgic Aeanoid via the Nostalgic Aeaonid Instructions and then potion the toy with Melody Essence.

Once you have your Common. Steamwork or Nostalgic Aeanoid, make a Nuclear Potion in the Genetech Lab (long and complex) or buy one from someone. Use the resulting potion on your pet (do not choose Feed).

Ty v m for taking the time for such a detailed explanation! :)

Hm! A bit of hard work ahead!

Edit - chose the Vanya method!

you are welcome. Different methods are cheaper/easier depending on the time of year, so it pays to know them all.

If I can butt in and expand on that, where do you go to grow the seeds? I can't remember! Thanks in advance!

You need to visit the Gardens in Veta Lake - then water the Aeanoid Seed for two days after planting and when it's grown, the plant will grow and bite your active pet and turn it into a Common Aeanoid.

Navigating to the Gardens you need to go to Veta. click the small barn and silo in the upper middle right. The fields next to the barn and silo are actually a game.

and Thanks for your help!!!!

You are welcome

You're welcome! Happy holidays! :)
