Help-Need idea to fix Jack-O-Lantern

Anyone have a fun idea to fix an ugly problem? I picked up this Jack-O-Lantern at Walmart a couple years ago and love that it's over-sized, a good 16" tall. I also love it's happy face:@) The problem is that they put the light bulb right in the middle of the back of it's head and you could see the bare bulb. This decoration goes in the kitchen so I didn't want that glaring light.

I did manage to make a hole at the top and move the bulb, that works much better. 

But it left an ugly (and distracting) indent in the middle of the back of it's head.

My son used a Dremel and cut the indent out...

How can I hide this 2 1/4" round hole? Simply putting cardboard, etc, over it still looks odd.

This has had me stumped so I thought I'd put it on the blog and ask for ideas... 

The pumpkin is one piece and the only holes are the cut-outs in the face (and now back of the head). 

It's also a harder, tough plastic and not made of the funkin material.

Lately I've been thinking about "stuffing" the inside of the pumpkin with crumpled deco mesh? 

...as you can tell by that thought, I welcome all suggestions:@)

Thanks and have a happy day!

PS-You can see what I did HERE, thanks for the great suggestions everyone:@)
