"Aaaah!" Calvin yelled after seeing the spinosaurus.

"Quiet!!" Hobbes loudly whispered to him, placing his paw over Calvin's mouth. "You could've gotten us killed! Don't make a sound or move at all, 'cause if big 'n' ugly sees or hears us, we are dead meat!" Hobbes said using threatening words to get Calvin to work with him. "Now just move back... very... slowly."

Calvin and Hobbes moved back extremely slowly trying not to capture the dinosaur's attention, moving even just millimeters at a time. But after only a few feet Hobbes tripped over a root and fell to the ground. The spinosaurus saw this and started to chase after the duo. "Aaaaaaaah!! C'mon, get up, Hobbes!! C'mon! Run!!" Calvin said, trying to pick Hobbes up who, obviously, was trying to run as well. They ran across the plains as fast as they could, the dino close behind. At last they reached the forests and hid inside the thick wood where the spinosaurus could not reach.

"(huff) (huff) I think we're safe for now, Hobbes," Calvin said to him, wheezing and breathing coarsely. "I wouldn't think we would have gone all the way back to the prehistoric age! What do you know, F. Calvin was right! Let's try getting back to the time machine now that the dinosaur we've escaped!"

"(huff) Uh uh," Hobbes said, also wheezing. "Listen, if we go back through the praire the dinosaur'll terminate us. And if we travel through this... jungle, we're bound to run into some creature that will tear us to shreds, limb by limb. We might as well stay here and plan an escape."

"No way! I'm going now, and that's that!"

"Wait!" Hobbes said, grabbing Calvin by his arm right before he was about to go through the jungle back to the time machine. "Wait! I mean it! I can plan something to get us back to the time machine no prob! Just give me a chance, okay?"

"Hmmmmm. Well, alright. But what's the plan? What could possibly get us back safe to the machine?"

"Okay. But first I want you to answer me. Now, what's the first thing a dinosaur does to detect you?"

"Uuuuh... He sees you?" Calvin guessed.

"No."

"He hears you?"

"No!"

"Look, does it even matter if I tell you? Just tell me!"

"Alright, alright," Hobbes said, "he smells you. My idea is that if we douse ourselves with mud, we'll lose our original scent and ugly over there won't know where, what, or who we are."

"But then he can see us!"

"Hold on! I'm getting to that! Now, my second idea is that if we uproot two bushes we can hide under them and carry them along with us we could go unseen by the dino. That leaves hearing. I guess we'll just have to be really really quiet."

"Okay, then, let's get started. There's a mud puddle over there, and those two bushes look quite adequate," Calvin said, pointing to all three of them. Calvin and Hobbes jumped into the mud puddle and bathed in it to lose their scent. After they got out they reeked of pungence; the spinosaurus would never recognize their odor. Next, they cut off two bushes from the ground and took them out to the field where the spinosaurus was; it hadn't moved an inch. They were ten yards away from the dinosaur and two hundred from the time machine. Every time the dinosaur turned around away from them they would run as close as they could get to the time machine. Then, when it turned back around, they would hide under the bushes unseen and undetected. Eventually they were only thirty yards away from the time machine.

Without thinking, Calvin yelled out, "Alright!" The spinosaurus turned around and began to chase after Calvin and Hobbes.

"You idiot! Hobbes shouted. "We're goners now!"

"Hey furball! Takes one to know one!"

"I knew I never should've gone on this stupid time trip!"

"Yo, fuzzy! Shut your trap and start runnin'!"

And the duo did. They ran like little cowards as fast as they could back to the time machine without their bushes and with the dinosaur following close behind. At last they reached the time machine. They jumped in quickly; the dinosaur was only ten yards away from them. Calvin pushed the time ignition button and the two swirled into the vortex of time, barely escaping the spinosaur.
