PRODUCT DETAILS
What's in the Box
- Red jumpsuit with white chest stripe and wrist cuffs
- Green foam-padded ankle cuffs (attached)
- Stuffed tail sewn to back
- Oversized echidna headpiece with 3D spikes and chin velcro
This Kids Knuckles Costume turns your child into the strongest guardian from Sonic the Hedgehog. The bright red jumpsuit has Knuckles' signature white chest stripe and white wrist cuffs, while the oversized headpiece features three-dimensional echidna spikes that stand up just like the game character.
The jumpsuit fabric is a cotton-poly blend knit that moves with your kid — no stiff costume cardboard here. Green foam-padded ankle cuffs are sewn on permanently (one less thing to lose), and the stuffed tail at the back completes the echidna silhouette. The headpiece secures under the chin with adjustable velcro tabs so it stays put during Book Week parades or backyard races.
Perfect For
Book Week & Video Game Character Days: Knuckles appears in Sonic the Hedgehog books and comics, making this a spot-on pick for literature-based dress-up days or gaming-themed school events.
Halloween & Costume Parties: Officially licensed Sonic costume means your child gets the real deal — accurate colours, proper character details, and instant recognition at trick-or-treat or birthday parties.
Sibling & Group Cosplay: Pair with Sonic and Tails costumes for a full team look at conventions, photo days, or family costume events.
How to Wear It
Pair with red or white sneakers (boots not included). The headpiece velcro adjusts to fit securely — test it before the big day so your child knows how it feels. Skip gloves; Knuckles' white cuffs at the wrists are built in.
Parent FAQs
Q: What size should I order?
Check the size chart image for chest and height measurements. The jumpsuit is form-fitting through the torso with a bit of stretch — if your child is between sizes and prefers looser fit, size up.
Q: Can they wear this over regular clothes, or is it meant to go on alone?
The jumpsuit is designed to be worn over underwear or a thin layer. It's not bulky enough to go over a full outfit, and the snug athletic cut works best without extra bulk underneath.
Q: How do I wash this? The headpiece looks delicate.
Hand wash the jumpsuit in cold water and air dry. Spot-clean the headpiece with a damp cloth — don't submerge it, as the fibre-fill spikes need to keep their shape.
Q: Is this suitable for outdoor Book Week parades in warm weather?
Yes, but it's a full-coverage jumpsuit, so your child will get warm if the day is hot. The fabric is breathable knit, not fleece, which helps. Have water on hand and consider a quick costume change after the parade if it's a scorcher.
Care: Hand wash cold, air dry. Spot-clean headpiece only.
