I was about to make a seperate Aquatic upgrade topic, but I realized there is a need for a list of all upgradeable non-wild pets sorted by family. If you want to rate them based on PvP/PvE usability, be my guest, but my basic idea was just to see what non-wild uncommon(or lower) pets there are out there, sorted by family. If there exists a similar pet with the same breed id obtainable from the wild, please note in the list what replacement pet+id there are, since its not really a must-use-upgrade-stone kinda pet.
I'll start us off, by listing the aquatic non-rare pets, since the two first stones I got were aquatic. Feel free to correct it, or even contribute with your very own family list that others can correct. I'll try to update this first post as more and more lists are posted, to keep it all neat and tidy.
Aquatic non-rare non-wild pets
- Sea Pony
- Fishy #22/ Tiny Goldfish #21
- Mr. Chilly(same as Tundra Penguin #9)
- Shore Crawler(same as Emperor Crab #4 and Shore Crab #3 + #7)
- Tree Frog(same as Frog #12)
- Wood Frog(same as Mojo)
As you can see, 4 of the 8 pets in this list has rare replacements elsewhere. Speedy and Jubling has replacements, but not with the same breed id. Sea Pony and Fishy(or Tiny Goldfish) are therefore perhaps the best options. I'll opt for Fishy first, just because he has a few health points more.
