The parents being shiny doesn't increase the chances of obtaining a shiny egg. The chances of obtaining a shiny are really high in this game though, so there really isn't much of a need to increase them with anything.

I've looked into it and apparently that balm mushroom is the only one in the entire game(?) If you sold it then the Spyce fetch quest is incompletable in your save file, unfortunately. If someone were to trade away their balm mushroom then the quest would also be locked away for them. The prize for completing it are a couple left overs, which eventually do become an unlimited resource through pick-up, so it's not that big of a deal, I guess. I have a couple extra left overs so we could just trade those to you and then you can pretend you did complete the quest lol.

The one event I have missed so far is the Bounsweet one, if you can get that, ut'd be swell. The Tangela is ready. My trading username is TailsFx.

I can breed one for you. If you want a specific nature tell me. If you don't mind I would like something else in return. I'm trying to complete the pokedex and there are some Pokemon I have missed.

Hello! I can provide all of those. I am on my own quest to complete the Pokedex and the only event Pokemon I've messed up on so far has been Bounsweet, so if you can provide that one or an evolution it would be appreciated. Just reply so that we can coordinate when to make the trades.
