After several bouts of communication with Mr. Business, your butler, you managed to get him to put a grappling hook into the central IV system at the center of your house which allows you to basically sync your sylladex with the internet around the world. IV has capabilities of this, perpetuating the reach of your sylladex. Otherwise, you could desync your sylladex, and maybe lose an item. Additionally, if you have a lot of items or a very confusing fetch modus, then you can look it up at www.mysylladex.wdg and find what you're looking for there.
That's also one of the websites you can buy certain modi that you wouldn't otherwise be able to find. That's how your friends got their modi. Syb from a NES bundle, Meowrage from the store, and Mew Mew from the board games bundle.
You fire that aforementioned grappling hook to the frog temple.
