i feel as if you should make a 1x1 hole anywhere on land (or maybe even hiding somewhere in the ocean) and it opens into a giant cavern and pokemon that spawn there are: Kabuto Kabutops (lvl 40 - trainer lvl 14) omanyte omastar (lvl 40 - trainer lvl 14) aerodactyl (but very rarely) because i think its not really fair that these pokemon can only be found in an egg thank you for reading !
Ya totally agree. There not that good in battle and I kinda just want them for collection sake. Maybe you can find one fossil in the cave behind mythical keep. It really well decorated but useless.
