John Paul Mercer, affectionately known as J.P., is the kindhearted, delightfully quirky member of the Stump Kids from Cartoon Network’s hit animated series Craig of the Creek.
Always ready for an imaginative adventure, J.P. wanders the neighborhood creek alongside his best friends Craig and Kelsey in his oversized sports apparel.
His bright personality and instantly recognizable outfit make him a fantastic choice for cosplayers looking for a fun, budget-friendly costume.
Whether you are attending your first convention or planning a group cartoon cosplay, this comprehensive guide will help you assemble every detail.
Complete Costume Breakdown
Clothing & Core Pieces
The defining staple of J.P.’s look is his vibrant, oversized orange hockey jersey that dominates his silhouette.
To capture his cartoon proportions accurately, purchase a hockey jersey that is two or three sizes larger than your normal size.
The jersey should hang down near your knees with roomy, slouchy sleeves that give off a relaxed playground vibe.
Customize the jersey by adding horizontal white stripe details around the sleeves and hem using standard white fabric.
You can attach your white fabric strips using permanent fabric glue, iron-on fusible webbing tape, or a quick sewing stitch.
Pair the oversized jersey with a classic pair of tan jeans or relaxed-fit khaki denim pants.
Choose a straight-leg cut in a warm khaki tone that peeks out comfortably beneath the bottom edge of your jersey.
For footwear, slip into simple black sneakers or casual lace-up deck shoes suitable for trekking through outdoor creek environments.
Accessories & Details
J.P. is famous for his spiky, bright ginger hair that sticks out in playful directions all day long.
A short orange synthetic cosplay wig is the quickest way to achieve his cartoon hairstyle without dyeing your hair.
Use a small dab of hair wax or pomade to style the front bangs into soft, tousled spikes.
Apply subtle faux freckles across the bridge of your nose using a brown eyeliner pencil or cosmetic freckle pen.
Carry a few fun accessories like a toy walkie-talkie, cardboard tube sword, or snack pack to complete the creek explorer theme.
Cosplay Tips
1. Always size up your orange jersey to replicate J.P.’s baggy, slouchy animated appearance effortlessly.
2. Test your fabric glue on a small hidden patch of fabric before gluing stripes to avoid staining the jersey.
3. Wear moisture-wicking undershirts beneath your thick sports jersey to stay cool during long, crowded convention days.
4. Keep your wig secure and comfortable by using a breathable wig cap and bobby pins around your hairline.
5. Break in your black walking shoes beforehand to prevent foot fatigue when walking across convention show floors.
