Initially,I only wanted to post this since I was a bit bored.Alright.First,you have to prepare a Golden Eggwich.Second,defeat DMG at the school festival.After that,go to the forest,you must have noticed there is a passage near the place where Bastion frequently visits,correct?Pass through there.You will find DMG.Talk to her.Give her the Golden Eggwich,then talk to her again.She will then offer to become your partner.Nicely done.
