My friend and I have been trying to figure out where to get Manjimutt and Roughraff. They're both needed to summon Dandoodle, but so far the only way we've found to get them is with the Select-a-Coin at the start of the game. The ones you get in this way, though, can't be traded, so it makes no sense that they're strictly there. Has anyone found them elsewhere?
This video helped me. I am not sure if there are more locations but you can do what he did, seems simple enough. Also this may help as well : Locations
