I joined PUSSTEEM yesterday and powered up some PUSS, so I think I can drop an answer.

chore: I'd ask him to make me Marquis of Carabas and get me a big castle to live in.

snack: Not sure, maybe fish and chips?

game: Chess, but only after he gets me the castle.

By the way, if you don't mind, I'd really appreciate it if you vote for me as witness. My witness account is @jswit. Thanks!
