I think they got that slogan from American coins. Because on the coins it says "In God we trust." They just changed God with Odd and made a nifty slogan from. That is my favorite Oddworld premotional slogan. Munch had a number of slogans infact the first Munch slogan was "May Odd help us."
Then they had "Powers up to the People", then "A Screaming Good Time."
