"That toy is in the bedroom."
Translation:Aia kēlā mea pāʻani ma ka lumi moe.
I think I see where you're coming from. If you were saying "That is a toy" you would say "He mea pāʻani kēlā". With a "He" sentence, there are two parts. Something is a something. That is a toy. So in that case "toy" and "that" are different parts of the sentence. If you were saying "That toy is a ball", however, you would say "He kinipōpō kēlā mea pāʻani", where "kēlā mea pāʻani" is one of the two parts, i.e. "that toy".
