Poor Peter the Shelf Elf was snapped into non-existence by the deranged Thanos. The boys awoke to a pile of dust that was once our faithful Shelf-Elf. His candy cane dust and some clothes were all that remained.
The boys were tickled to dust over the whole thing.
Peter was a good Shelf-Elf but it was time to usher out the belief in myths and I suppose Thanos came along to help. Still, it is a little sad...but more funny than tearful :)
