This is the steps to Henry's monster ....

#1 draw a dark blue head kinda square shape.

#2 make his body like a half a circle.

#3 make the top of his body the same kind of blue as the head, the middle is light blue, and the bottom is regular blue and the body is done.

#4 and to finish the monster, the rest is to make a W shaped mouth that is red and to make his eyes orange.
