Killy Willy is a popular fan-made monster from the Poppy Playtime community, often depicted as a discarded, multi-eyed, black-furred version of Huggy Wuggy.

How do you make a DIY Killy Willy mouth?

Cut a large crescent shape out of red felt for the mouth, then cut out several small white felt triangles for the sharp teeth and glue them along the edges.

What is the easiest way to add the eyes?

Peel-and-stick large googly eyes are the fastest method, but sewing or hot-gluing felt circles is more durable for a long night of wear.

Tips
