Slappy- Animating Dino Skeleton

“Maybe my prehistoric friend will teach you a lesson!” Slappy shouted.
He raised a hand and motioned to the end of the hall. Then he cried out some strange words I couldn’t understand.
I heard a crash. A loud thud.
I turned in time to see a skull appear from the room at the end. The head of the dinosaur.
Bobbing on its three legs, the dinosaur skeleton came clattering down the hall. It tossed its giant head back. Its jaw moved up and down, stretching.
Shannon and Logan screamed. No one knew where to hide. We tried to crouch behind a display case. Aaron hid behind a statue. But no place was safe.
The mummy dropped Slappy to the floor and turned to see what the commotion was.
“My dinosaur friend is very hungry!” Slappy cried. “You’ll make a nice meal for him, Mummy Dearest. We’ve got to put some meat on his bones! Hahahaha.”
The foot bones hit the floor hard. The dinosaur head bounced. The jaws snapped. The enormous skeleton filled the hallway, scraping the walls.
Everyone turned as it lowered its head to attack and came rattling on its three skeletal legs, closing in rapidly on the mummy.
“Have a good meal!” Slappy shouted to the tall dinosaur skeleton. “I hope he isn’t too dry for you! Hahaha.”
...

The mummy staggered back, eyes on the dinosaur’s massive snapping jaws high above his head.
The dinosaur threw a deep shadow over the floor, over all of us, as it moved. Balancing on its three legs, it tossed its head high. Then opened its jaws wide and zoomed down to feed.
Arragotus raised a fist—and slammed it hard into the dinosaur’s open jaw. A powerful punch that sent a craaaaack that echoed off the walls.
The jawbone fell off and hit the floor, bouncing to the wall.
Arragotus landed another punch—and the head flew off. The rib bones clattered free. The leg bones collapsed.
In seconds, the dinosaur crumbled to pieces. The bones fell in a heap on the floor, rattling noisily.
With a roar, the mummy raised his fists in triumph.
“Oops!” Slappy cried. “I guess dinosaur dinnertime will have to be postponed!”
