Ok, I'm trying to figure out how Subaru should be summoned. Like what he was doing before Satella brings him there. It could be through some mysterious pipe he came across while on another one of his adventures with Mario and Luigi, or I could go the same route as Bowser's Inside story, or maybe the Mario Movie route which would have spoilers. I'll be asking the same thing on my Undertale Subaru story as well. So, any ideas?
