A family of aliens

Our 5 year old grandson was drawing pictures after school That’s him as an alien on the left. His little brother is on the right. That’s me, Granny in the middle with three eyes and no mouth. At the bottom is a dog alien with a very long tail. The sign says ‘ NO’ short for ‘ NO aliens here’ amusement all round for a good 15 minutes. His little brother isn’t feeling quite right and fell asleep on my lap in the middle of the drawing.
