Reader Nina used the Perry the Platypus costume idea from October to create this fun Perry costume for her daughter. I love how she made the one piece Perry body (since she couldn’t find green sweats) using a sweatshirt and sweatpants of hers for the pattern. According to Nina: “We cut a line down the back so she could get in it, and used strips of matching fleece to make two ties to hold it closed. We followed your directions for the beak, feet, and tail, and it came out fabulously. She loves it and wears it as often as she can.” The Boy still wears his all the time too! All hail Phineas & Ferb!
