There is a bug of some sorts with looting the spider, if you loot the grey items before anything else you are locked out from receiving any other loot. If you're only after the Toy, the best tactic as of yesterday has been to kill the spider check the loot for the toy, if it didn't drop DO NOT loot anything. Then you can wait for it to respawn(I've heard relogging automatically respawns it) and rinse and repeat until you get the toy. Just make sure when the toy does drop that you loot it first.
