A Quokka Dreeds its Weird

Like a total fool, I brought inside groceries consisting of pricey organic eggs, butter, and ice cream inside last night, then didn't notice them till now. (About 17 hours at room temperature.)

Is any of this salvageable if I refrigerate it now? The butter at least should be, right? I know that many non-Americans are not so refrigeration-happy and are just fine. It's not a hot day.
