First squirt some yellow craft paint on the paper plate. Go ahead and paint your toilet paper rolls completely yellow. You don't even have to cover the whole roll, but if you do - no problem! I just say the whole thing doesn't have to covered, because one half will be covered with the blue construction paper.
Once you got the paint down, set them aside to let it completely dry.
While you are waiting, cut your construction paper pieces out. Out of blue construction paper I cut strips for the minions pants and the gray & white I did the goggles/his eyes.
Once your toilet paper rolls are dry, it's time to hot glue it all together. The strip of blue cardstock paper goes around the bottom to give them pants. The eyes will go towards the top, right above his paint.
To finish them off, draw on hair & a smile. And you are done! Play with your cardboard tube minion like he is peg doll!
