Spread thin layer of Nutella on each crepe, then cut into strips 2 inches wide. Pizza cutters work great for this.
Wrap each banana with one or two strips of crepe, then slide onto skewers to help hold the shape. Two rolls per skewer.
Add candy eyeballs.
Notes
If you can't find candy eyes, they're easy to make with melted white chocolate and a piping bag. To mix things up, try with peanut butter instead of Nutella.
