Step 36: To the front of the head, attach a grey 2x3 plate.
Step 37: To the 2x3 plate, attach a chrome 1x2 tile with grille, two grey round 1x1 plates, and two transparent blue round 1x1 plates.
Step 38: Attach a grey 1x2 tile centered onto each one of the grey round 1x1 plates.
Step 39: Attach the entire head assembly onto Joebot’s body as shown.
Step 40: Lastly, and MOST IMPORTANTLY, swivel the grey 1x2 tiles downward at a 45 degree angle, thus forming Joebot’s sad, droopy eyebrows.
Congratulations! You did it! You are the proud owner of your very own neurotic, morose robot!
