Alien and Monster

Mommy found Shenny concentrate in drawing something at table this afternoon. Mommy asked her only after she has finished drawing.
Her explanation of her drawing roughly like this.
I have drawn Monster and alien. Monster is very happy because he has a lot of food. Alien is a bit happy only because he has a little food. Alien is surprised (his mouth is in '0' shape) to see "earth" can talking. Earth has arms and legs. He can dance.
