Translation:I will find pencils and draw a picture.
Does it mean the sketch for a painting? Or drawing a picture with colored pencils? Either a word or a different definition/use of a word is not clear in this example.
I will find SOME pencils, not "find pencils." Pencils is not a location or a proper noun. You need to identify how many or which specific pencils you want. If that information is unknown, you have to express that by saying "some" pencils.
