A 36x36 foam sheet, a blue salad bowl, some blue craft foam sheets, some black sharpies, and some silver spray paint.
R2's head was one quick trip to the dollar store. Some LED keychains, a magnifying glass and some cheap swivel water tap heads.
Hope you guys like.
P.S. I'm just glad he didn't ask to be M.O.D.O.K. , another one of his favs.
