Dip hard boiled egg in blue dye first (only half) to desired strength of blue color for pants – when dry do the same with the other half but in yellow. When dry glue on googly eyes like shown in examples. Use sharpie marker to create smiles and rings to top and bottom of eyes. Pictured they used black yarn to create band for glasses but you could just finish with sharpie marker. Very cool and the kids will love their new companions.
