I'm surprised you even find Shelgon in the first place considering it isn't... well wild in any games (-XY Friend Safari and SOS)
The catcher is not like the games and not meant to be like that so yeah we can find Shelgon along side a few other mons you might not find wild in the games. The evolved mons tho while there are harder to catch, much harder so is not like people can just go out a grab them easily.
We aim to give you all an unique and good experience with the catcher, so far it seems to have worked pretty well, and people like it very much.
All of my major favs and almost all of my minor favs have been added (Only missing Latias, Victini and Palkia)
Ah, but when will the third set of Legendary Eggs be released? If memory serves, the large 3rd update did not introduce its legendary species yet, which means they're still yet to come. I suppose that will be a matter of where and when, and we will one day find out.
I hope triple colored, like red one side and blue the other with a green stripe going down the middle. If they'll even be introduce as eggs, kinda hope because they'll probably be a huge pain to get other wise.
Or maybe they'll be chrome-coloured! ...or neon red-blue. There are a lot of shades of those two colours besides their 'default' natures.
Mm, has anyone unearthed any Fossils yet? I may work on one of those to record the data for the Catcher Dex. I think I'm nearly done (or so I hope!) with my current one, and would like to decide my new project.
