Slappy- Propane Tank Explosion

They fought along the garage wall. Then they stumbled into the yard behind the garage.
“The propane tank!” I shouted. “Stay away from the propane tank!”
Gasping for breath, I reached the back of the garage, turned—and saw the tall tank tilting slightly away from the garage wall.
...

We saw the battling, punching dummies stagger and stumble toward the tank. Screaming and groaning, they punched and wrestled—and tumbled closer … closer …
And then all three of us cried out as Slappy picked Snappy up off the ground—and heaved him with all his might into the tank.
I shut my eyes tight. I held my breath.
Would the tank explode?
...

Yes, it did.
I heard a bump as the heavy tank hit the ground. Then I heard a crackling sound, like the crack of distant thunder.
And then the thunder wasn’t distant. It was right overhead. Then it was all around, a deafening boooom that hurt my ears, shook the ground, and made the hedges in front of us tremble.
I opened my eyes in time to see a wall of flame shoot up like a tall wave over the back of the garage. I felt a powerful burst of heat against my face.
Like a strong, hot wind, it pushed me back and flattened me on the ground.
It swept over me with a roar, drowning out my shrieks of horror.
I raised my head in time to see the garage burst apart. The roof flew up, and the walls crumbled and fell. And as the roof sailed to the sky, spinning as it rose, I heard shrill screams.
The dummies screamed and wailed as they were blasted into the air.
Their arms and legs fluttered in the explosion as if they were swimming.
One of them sailed high and far. Squinting into the hot flames, I saw him swoop over the trees, down the sloping hill. It looked like he might fly forever. He was gone in a few seconds, out of sight.
...

Wow, dudes. That ending was a BLAST—wasn’t it?
I was sorry to fly off without saying good-bye. No one even wished me “Happy landings!” Hahaha!
At least those kids got their drone to fly. Too bad the rest of the garage had to fly with it! Haha.
Well … don’t worry about me, slaves. I don’t go to pieces when these little accidents happen. I’ll get myself together real soon.
Don’t think you can escape Slappy. I’ll be back before you know it with another Goosebumps story.
Remember, this is SlappyWorld.
You only scream in it!
