Slappy- Projectile Vomit

But I looked down and saw Eddie still frowning. “That isn’t very funny,” he called up to me. “Can’t you be funnier?”
“You want funnier?” Slappy suddenly shouted. “I’ll show you something funnier, kid!”
I gasped. I hadn’t made Slappy say that!
Before I could do anything, the dummy tilted back his head. He opened his jaws wide.
I heard a gurgling sound from deep inside Slappy’s stomach.
And then I cried out as the gurgling grew to a roar.
And a thick green liquid poured out of Slappy’s open mouth.
It gushed out like water from a fire hose. Thick green gunk. Thick as pea soup.
Slappy turned his head and sprayed the green goo over the kids. It splattered Eddie Simkin at my feet. Splashed over the walls, the floor. Sprayed over the other kids.
“Ohhhhhh. The smell!” a girl cried.
A foul, putrid odor rose up all around.
Slappy tilted his head back further. Turned. The disgusting green liquid spewed over everyone.
Kids squealed and cried out in disgust. I saw a boy stand up and try to run. But his feet slid in the green gunk, and he toppled back to the floor, facedown in the goo.
“It’s in my eyes!” a boy screamed. “It’s burning my eyes!”
“Ohhhhhh.” Moans of horror and disgust rose up over the basement.
I tried to slap my hand over the dummy’s mouth to stop the spray.
But Slappy jerked away from me. I cried out as he slid off my lap. He dropped to the floor. Stood on two feet. Tilted up his head and spewed out more of the stinking, thick liquid.
Kids were trying to scramble away. Some were crying. I saw two boys bent over, vomiting on the floor.
