.. How to find the provisions?

You shouldn't eat on the sofa! Click on the sofa.

Those wasabi peas will make good provisions for the journey. If you pick them up now, they would be all over the place.
Maybe some kind of container would keep them in one place.

Maybe something oily...

There is an oil can in Rufus' room bench.

Well, obviously you can't fill the can full of oil with peas. Get rid of the oil first.

Where wouldn't nature lover like you pour oil into?

Just pour the oil to one of the sinks and use the empty oil can on the sofa.
