Unfortunately for Fievel, the land around him didn't seem to have that much food and water. Just as he was about to faint with hunger, he stumbled upon a large valley that had many trees and streams. "Finally!" he cried in joy.
He drank from a large stream for several minutes and then climbed up a large tree and ate as much fruit as he could until he was full.
It was now getting dark and he was very tired, both from his lack of sleep inside the various creatures and from his large meal. He didn't want to fall asleep where he was because he feared he'd fall out of the tree and break his neck. However, he was so tired that he couldn't hold off sleep. Luckily for him, he didn't fall out of the tree and break his neck. However, he was still not out of danger.
Fievel slept all night and was still asleep three hours after sunrise. At this time, Bron, an apatosaurus, had come to the valley, which was called the Great Valley, to visit his son Littlefoot. As there wasn't as much food outside the Great Valley as inside of it, he thought he would help himself to eating the various plants. One of the areas where he feasted was the tree that Fievel was nestled in. Thus, Fievel found himself shaken awake as Bron put the leaves he was nestled in into his mouth, taking the mouse with them. The mouse was moved around in the mouth as Bron chewed. Thankfully he avoided the teeth but he still was coated in saliva. He cried out but his small voice couldn't be heard over the huge sauropod's chewing. Soon, Bron swallowing, sending Fievel down his throat with his food.
Fievel fell into the stomach, which was thankfully devoid of acid, but did have several gallons of water in it, which Fievel landed in with a splash. Thankfully, the water wasn't all over the stomach, so Fievel was able to wade out of it. Food continued to dump into the stomach as Bron continued to eat. Fievel looked around at the huge organ around him. It was several times larger than Ozzy's or Mo's had been. It could fit his whole family in here two hundred times over and still have enough room to move around comfortably. Large or not, however, it was still a stomach and that meant digestion. He had to find a way out of here or else he'd be digested and turned into dinosaur poop. He soon found the entrance to the small intestine, but the muscles were too tightly sealed for him to open, far harder than it had been to get into Ozzy's duodenum.
Nevertheless, he still pushed and pulled at the sphincter, desperately trying to open it enough to squeeze through. He was still at it, though tired, hot, and sweaty, six hours later when food and water once more entered the stomach as Bron had his lunch. He had, naturally, tried crying out to Bron to spit him up after being swallowed. However, he eventually saw that it was no use. Considering how loud the sounds of Bron's heartbeat and breathing were to him in the stomach, there was no way that his tiny voice could carry past the thick stomach wall and flesh to the outside. Thus, he could do nothing as he was pelted with large chunks of chewed up fruit and doused with gallons of water.
An hour after this, he began to hear the familiar sound of a gurgling stomach, indicating the start of digestion. "Oh no!" he cried in panic. He tried harder than ever to push his way into the small intestine but the valve wouldn't budget at all. Acid began to enter the stomach. However, much to his surprise, though it stung his skin and felt hot to the touch, he wasn't suffering serious damage. Luckily for him, Bron's stomach acid was made for the digestion of plants, not meat. Still, that didn't mean that Fievel was out of trouble.
Every now and then, Bron's stomach would contract as it processed the food. The strong stomach muscles continued to knock the wind out of Fievel's lungs. Finally, he decided it was best that he squeeze himself into as tight of a ball as he could so as to minimize the damage to his lungs from this squeezing. His muscles ached terribly but now he could breathe better. He was coated by the food that Bron had eaten, getting his clothes caked in digested leaves and fruit. He stayed in the stomach for nearly 30 hours in total, getting coated in Bron's dinner and breakfast and lunch as well. His body was terribly aching from the constant contractions and being curled up into a ball when finally the stomach began to drain. Soon, he was squeezed into the small intestine.
Fievel spent 16 hours in the small intestine, being pulled at by villi. It was a long trip as the dinosaur was huge. Finally, he entered the large intestine.
In here, he was coated in huge dinosaur poop. Despite his best efforts, he was totally encased in it and only was able to free his nose. Worse for him, loud and smelly farts moved past, brought on by Bron's vegetable diet. He was glad, 12 hours later, when he reached the rectum. Unfortunately, Bron had recently pooped two hours ago, so it would be a long wait.
After waiting in Bron's rectum for 60 hours, during which time he had puked a few times due to the overwhelming smell of dinosaur waste, Fievel could finally sense that Bron was going to defecate. He could hear many loud farts and the chamber began to move as the muscles in the rectum began to propel the waste forward toward the anus. He would soon finally be out of this large dinosaur.
Bron, his tail raised out of the way of his cloaca, grunted. PPPPPPHT! PHHHBTT! PHHHHH! Loads of gas exited his cloaca. Soon, a large log of poop began to descend out of his open cloacal slit, making a loud PWICA sound as it moved past the vent. Fievel, meanwhile, soon reached the gaping anus and was squeezed through it into Bron's cloaca. A minute later, he was pushed through the vent and fell many feet to the ground, luckily landing in some poop below, which broke his fall. For the next several minutes, more and more logs of solid waste fell on top of him. Luckily he wasn't buried too deeply. Then he was doused with several gallons of urine as Bron peed for two minutes straight. When the apatosaurus was done relieving himself, he shook his cloaca to remove any solid waste that was stuck to it and then walked off, leaving Fievel alone.
It took Fievel three hours to dig out of the pile of Feces and another two hour to wash himself and his clothes until he no longer smelled like the butt of a dinosaur. By this time, it was starting to get dark.
After eating and drinking again, he left the Great Valley, in search of the time machine. He hoped he wouldn't be eaten again. Alas, it was not to be.
