Hello all, Spino here ^_^
This is truly an awesome and excellent art piece -a YCH that  arcticdunx and  Sergeant_Stacker (me) we talked about in skype together
Check out the original one here, and give arcticdunx's gallery a gander too!: http://www.furaffinity.net/view/21794770/

Dunx and myself decided on Halloween to have a little fun -Arctic would lure some little two leggers to a cave nearby, while Spino wondered what to do. He then explained the custom of little ones like himself "dressing up" and hunting for candy during the night. Naturally such little sweets were nearly microscopic to the Dinosaur, but it had a plan: Dress up as a "cave", and the trick-or treaters would have to climb into his jaws to get at the "candy" inside Spino's belly. With cooperation, the "costume" was constructed, all the spined lizard had to do was lay down, poke his head out the front end, and open his jaws up, waiting like he would when fishing for his favorite food~

When Halloween night came around, the plan went off without a hitch:
 CommanderLeifN7, a dress suited land-shark sporting purple facial markings, eagerly climbed into and down the predator's gullet without issue, much to SPino's delight -Sharks are fish afterall- and maybe find some candy too!
 Ceterus, a ring tailed lemur came along next, eager to see what the hub-bub was all about, looking for candy, and decided to get candy too, their fur caked in saliva for the ride down, though all he found was the Shark rubbing the fleshy walls around him, and found acidic fluids warming him up instead!
 zephyrgold58, a cute Utahraptor wa curious what was going on -they clearly knew this was a large Spinosaurus, but what were the chances of tasty candy being pi[inside[/i] it? Well he wanted to know with some curious nature, and took the plunge too, managing to poke his head and claws in, trying to pull himself through the tight sphincter. Stumbling on the previous two morsels~
 Yamato_Okami and  hinataskywalker were walking through the forest together when they saw the pitched up signs telling of candy nearby, and saw the huge cave entrance, along with a loudish burp. The cave entry point seemed...fleshy and slimier than usual, smelling of fish, fur and feathers for some reason. Well that still didn't stop the duo from wanting in on the fun too -there was candy at stake, and no one liked going home empty handed!
All the while the Arctic Fox-sune looked on, licking his chops in excitement from these people and their antics, his tails swishing slowly.

Little did they know non of them would be going home at all~

Massive credit goes to  arcticdunx for making this exceptionally wonderful art piece, as well as  Sergeant_Stacker since it was a joint-operation idea

Credit also goes to the tasty morsels  hinataskywalker the Hybrid Raptor on my tongue,  Yamato_Okami the Wolf about to slide down my throat,  zephyrgold58 squeezing through my belly's entrance sphincter,  Ceterus the tasty Ring-Tailed Lemur sitting down in the gathered stomach acids, and last but not certainly least  CommanderLeifN7 the dapper alien land-shark massaging and rubbing my stomach lining~

Thank you so much again Arcticdunx, I really love and appreciate you and your excellent art skills!
