[Once the immediate shock has worn off, Goku's first order of business is to get some proper food. Then, finally, he realises that some things have changed... But it's not like he had time to get attached to anywhere before the flood started anyway. The Usyagi direct him to his new dome house (hey, Alice!) but he doesn't bother going inside yet.
Instead, Goku can be found sitting on the front step of the house with a giant bag (about two feet high) full of Chinese take out next to him. Right now, he's eating some dim sum with chopsticks in one hand and the note about monsters in the other. Honestly, the dim sum are occupying more of his attention, but the note is interesting too!]
They have monsters here, huh? ... Wonder what they want.
[... Screw it, he can worry about that later. Goku puts the note aside and starts going to town on the food.]
