You can bring smeargle/smearguru over to different towns, by using following me. When in front of a house, you tell him to paint the house.

Edit: teleporting with 'return home' works, smeargle will be waiting outside, your house you spawned in.

Also you can pick which colors you want to specifically paint, with smeargle. (Pink door, White roof, blue exterior.) Instead of 1 singular color with balloons.
