The way for the Onion Duck to evolve into an Onion Wanderer is rather specific, requiring the match to end after hitting the vitals 3 or more times in the match. It is best to have the Onion Duck carry an Onion, which will increase the Onion Duck's Hit the Vitals level by 2 levels. Players can catch Onion Ducks with Onions on Highway 5, and they will also encounter Fruit Weng on Highway 5. It is hard to kill Fruit Weng by hitting it with Shattered Rock, and it is very easy to trigger a 3-hit blitz.
