Butler- Collapsing Circus Tent

'Fine,' said Artemis. 'This charade is beginning to bore me.' He raised his palm to his mouth. 'Time for plan B.'

Outside the tent, Butler wrapped the tent's mainstay around his wrist and pulled. He was a man of prodigious strength, and soon the metal pegs began to slide from the mud that held them. The canvas cracked, rippling and ripping. The dwarfs gaped at the billowing canvas.

'The sky is falling,' screamed a particularly dense one.
...

Artemis noticed the silver orb in Holly's hand. 'Butler,' he said into his mike. 'We need to get out of here! Now. Northeast corner.'

He grabbed Mulch's collar, leading him backwards. Overhead the canvas was falling, its descent cushioned by trapped air.

'We go,' screamed Derph. 'We go now. Leave everything and dig.'

'You're not going anywhere,' gasped Holly, her breath rasping along a bruised windpipe. She twisted the timer, rolling the grenade into the midst of the Significants. It was the perfect weapon against dwarfs. Shiny. No dwarf can resist anything shiny. Even Mulch was watching the glittering sphere, and would have kept watching until the flash, had Butler not slit a five-foot gash in the canvas and yanked the pair through the gap.
