That's actually really interesting. Not by much but cool to hear. I never knew you could see him.
such is the magic of leitmotifing
Was the first Wario land about Wario invading a territory (I never bothered to read the manual) and making it all his? no, he invaded the territory because a massive golden statue of Peach was stolen, and wanted to reap the rewards for getting it back. Because in Wario Land Shake it, the plot is pretty similar, Wario invades foreign territory but this time he leaves it all to the Queen. What really stands out is that Syrup acknowledges that, learned how to persuade Wario and used him as a scapegoat.
Other reference I forgot, is that in Super Mario Odyssey you need money to buy costumes in order to progress the game the fuck are you talking about, all of those moons are optional, in a similar manner to Wario Land 1st: You had to spend money just to progress your path. ten coins to open a door isn't that big of a deal
