**NEW!!** This adorable yet tough plush monster comes in green striped minky material and has the message Mr. Mayhem embroidered on his back. He comes complete with his mask/cape made of black flannel, and his belt is made from heavy duty black vinyl with decorative pockets and buckle. The belt and cape can be removed. This costumed monster is just too much fun!

The monster can be personalized! To add a name to the front (on the tummy), just click here and add to cart:

Mr. Mayhem's Vital Stats:

-Size: 14in tall/10in wide (36cm/25cm)

-Machine washable, tumble dry to retain monsters soft and plush feel. Cape is Machine Washable, belt can be wiped.

-Upgraded faux down fiberfill used, resists bunching in the wash and gives the monster a nice heavy feel.

-Double Stitched to ensure durability.

-Long arms tie and hold tight to backpacks, strollers, etc., and will not fall off! Great for if your little one doesn't hold on to them the whole time you are out and about.

These monsters are made with love in a smoke free, pet friendly environment. I use only high quality fabrics and fillers to ensure your child's safety!

Thank you for visiting my shop!
