Like a Monster Out of Nightmare

"Bad idea", Jimbob thinks to himself, staring into the epicenter of the Octosaur.

He wraps just his torso around the two tentacles enough to secure them, which frees up his hands and feet. He uses his hands to free the Flash, and his feet to grab two more tentacles and hold them in place.

“What happened with my truck?” he wonders. He did hear a shattering, grinding crash, but he didn’t see any damage to the Octosaur, and unless it’s made of vibranium, he should have seen a big ol’ truck-shaped bruise, at the very least.

But that’s the least of his worries, as the glowing green bumps rising on his flesh detach, form legs, and start crawling up and down his limbs like radioactive spiders!

Oh, and the Flash is covered with green glowing spiders, too.

The Martian Manhunter takes the rope hand off from the Flash, and flies his end up to the top of the office building that is tilting and about to collapse. He quickly ties it taut around the most secure structure there, whether it be a lightning rod or water tower. Between being wrenched by the falling building and being run into by the Trusty Trailer, hopefully they can stun the beast long enough for the Flash to escape.

The ringing laughter then reaches his ears, and he searches for the origin of the mirth. Perhaps, just perhaps, he can confront the source of the creature and defeat it that way.

There, on a rooftop, is a man dressed in burlap rags with a pointy burlap hat and a face made of straw, with a crude face painted on it. He’s just loving this whole Octosaur thing.

"Ha ha ha ha ha! Cringe, heroes! Show your adoring public how you handle REAL fear! Ah, ha, ha ha ha ha ha!"
