There seems to be alot of Paper Mario influences in Oddysey, Some of the things Bowser steals seem to indicate that he learned from the last time he and Peach got married. The new snail race looks alot like the snail people from rogue-port, and they even made the forest Goombario lives in a canon part of the mushroom kingdom(plus the female goomba looks like she could be Goombellas mother).

So if the female goomba was in fact Goombella's mother, that would mean that Oddysey takes place before the Paper Mario series does? That would be interesting
