The Spoop Boop Mascot pair, with "Spooky" written all over them on the inside, and longer black fur insides.
 
The Spoop Boops! Built just like the Scream Kiwi Boops, but with a little extra spooky looking fur on the top.  These are by far the witchiest, and Spoopiest ears that have ever graced the Booped Warehouse's site.
