Twiggy/branchy? Stinger?

Where exactly do you find these creatures? I know they're rare and n/a in the book but I've not seen them outside of bot vs and PvE. Also the pre-evolution of Bush would be nice to know how to acquire...

I don't believe it's possible to get twiggy and branchy at the moment. You get stinger by having 5 people use your pal code and then reaching lvl 10. Idk if you can get the preevolved form of bush, maybe through eggs, but like I said, idk for sure.

Gralf the preevolution of bush is found in thorny forest 3

vet or reg?
