A/N: I'm only posting this chapter because I started posting this story last week. ;) Lol. And also because I just want the first story posted where I can post the second story. But before you read on, I need to ask you guys something.

It would probably keep the story interesting if someone wrote it with me. Yes, I am asking for a co-writer. ;) So, anyone who wants to be my co-writer, don't hesitate to offer. I'll look at your stories and see your writing style. That's all I need to know, really. Alrighty. Thanks to who have reviewed and also, don't hesitate to request one-shots for 'CasyxDiego 100 one-shot'; I'm stuck and need requests.

I hope you'll like the chapter.

Oh! And also, check my other account 'Princessofthewoods'; you can follow me on twitter, facebook, and much more. :) And if you have skype, go on and add me as 'Elizabethbecks'.

"Great news! I found a shortcut."

"What do you mean, shortcut?"

"I mean faster than the long way around."

"Ow! I know what a short cut is!"

"I have to agree on Diego on this," Casy spoke up, taking her place beside Diego. " Either we beat the humans to Glacier Pass or we take the long way and miss 'em." She didn't know about Diego's little plan. She thought that taking the cave would be faster and much better, rather than walking in a blizzer or five feet of snow. Manny looked at Diego.

"Through there?" he asked. The tiger nodded. "What do you take me for?"

"This time tomorrow, you could be a free mammoth," Diego said as the baby slide down Manny right side of his face and pulled on his eye lid. Manny yanked him off and sat him on his head. "Or nanny. Personally, I never get tired of peekaboo." Just then, Sid came along with two icicles in his hands.

"Hey guys!" he said, grinning. "Guys, check this out." He put the icicles on both sides of his neck and made a gagging noise. He tumbled a couple of times, making the noises again. Casy found this entirely disgusting. It was pointless to even play like that, or play at all when they had something seriously on their paws. When Sid was near Casy, she knocked the icicles out of his hands and earned an offended look from Casy. "Hey! I was using those!"

"And now you're not," Casy said simply, a small smirk on her lips. Sid gave her a look but turn his attention on Manny when he patted his shoulder.

"Sid, the tigers found a short cut."

Sid looked up at the cave he looked at Casy and Manny, obviously now fearing continuing on with the journey. "No thanks," Sid said, turning around to walk off. "I choose life." Casy and Diego were quick to get in front of Sid, giving him a dirty look. When it came to taking someone back to their herds, Casy would not hesitate on that.

"Then I suggest you take the short cut," Diego said in a low voice that made Sid back away from him.

"Are you threatening me?" Sid asked in a teasing tone, pointing a finger at Diego.

"Move sloth!" Casy yelled. Her voice echoed throughout the area. Seconds later, above them, big pieces to the ice that was attached to the cave began to crack. Sid patted Casy's head.

"Way to go, tiger," he muttered. Casy paid no mind to him, her eyes widening as the pieces began to fall.

"Quick!" Manny said, running towards the inside of the cave. "Inside!" The rest didn't hesitate. They sped into the cave, one of the pieces almost crashing down on Sid. They made it inside of the cave safely but more pieces fell down all the way to the top, trapping them inside. They heard light jiggling and they looked up, finding icicles shaking and they were right above them. The gang looked at each other before making their way to the entrance, but only to stop because of the rocks.

"Okay…" Manny trailed off, turning around and beginning to walk off. "I vote short cut."

The others followed them, Casy behind Manny and Sid walking beside her, behind Diego. Casy looked around her as they walked. She knew where exactly to go and what this cave was. The one good thing she was taught by her lousy father was that how to make your way out of a cave, especially an ice cave. It was one of the things that Casy was an expert at. She didn't notice that Sid had knocked himself out.

"Do you know what this cave is?" Manny asked no one in particular. Diego shook his head.

"I do," Casy piped up. She didn't mean to say anything but she couldn't but help to speak. Diego turned his head around and raised an eyebrow at her. "My father is an expert on caves." Diego looked at Manny for permission and Manny nodded. Diego looked back at Casy and motioned for her to come in front. Casy smiled and did so, letting out an "Hmph!" to Diego. He rolled his eyes as Casy got right in front of them.

"So…" Manny began after a few moments of silence. "What is this cave?"

"It's what humans use for protection if their tribe in being attacked," Casy replied. "They quickly pack some wood, raw fish, some blankets and gather up before the attackers can get to their tribe and head to this cave. They mostly do that when another tribe is going to attack them. They go here for couples of hours and send out one of the warriors to check their village." Manny and Diego blinked in surprise. Who knew one petite saber knew so much about a cave? Manny opened his mouth to say something but stopped when he saw Sid waddling behind him, trying to catch up.

"Will you keep up, please?" Manny asked in frustration. Little did Manny know that the baby got picked up by an ice slide that he was walking over, which somehow, Diego found a way to get on its side. "Hard enough to keep track of one baby."

The four then found out about the baby and watched him calmly as he slide towards an entrance of the slide. The baby then waved and dropped down.

Casy chuckled. "Isn't that cute?" she said. "That baby is taking a ride around this cave." But then everyone looked at each other, realizing that the baby had dropped and could possibly got hurt. The gang's eyes widened and they yelled.

"AHHHHHH!"

They rushed over to the entrance and found the baby sliding down a curve ice slide. Casy knew it was going to be long. So, wanting to get it over with, she jumped first, hearing Sid, Diego, and Manny doing the same thing. She tried to use her claws to stop from going too fast on the slide but the ice was too slippery. She felt someone bump against her back and knew it was Diego because she heard his grunt. Manny and Sid bumped up against Diego, making him push Casy a little more. They then flew up in the air, all four of them going in different entrances, Casy and Diego in the same one. They didn't stay in it that long, for they were flying all around the icy place. This time, Casy ended up with Sid, her sliding right behind him. He used his hands to speed up on the baby. He reached out his arms for the baby but couldn't reach him. Sid cheered a couple of times just for the fun of it and then he used his hands once again.

"I gotcha!" Sid said, grinning as he caught the baby around the waist.. Casy grinned herself and cheered.

"Go Sid!"

It was then that Sid dropped down a small hole, the baby going up in the air and landing on the other side. Casy almost went down with Sid but used her claws to hold onto the edges. Surprisingly, Casy managed to keep a hold on the edges and pulled herself up, starting to slide after the baby again. After many turns and ducking, Casy landed flew up in the air and saw Manny, Sid, and Diego. Sid was on Manny's tusks and Diego was clinging at the back of Manny. And unfortunately for Casy, she landed right on Diego, her paws going to his eyes. He grunted and moved her paws, looking up at her in annoyance. All Casy did was smile innocently. It was then that they saw they were sliding to a very thin, yet curve ice edge.

"Captain!" Sid yelled, taking Manny's trunk and talked into it. "Ice berg ahead!" (A/N: Hmmm...reminds me of something. ;) )

They stopped just in time and everyone breathed a sigh in relief, watching as the baby slid off. The ice they were on began to crack and began to lower down.

"Oh no," Diego said, his eyes widening.

"Oh no is write, my saber friend!" Casy exclaimed as the ice dropped down and began to slide. They all yelled when they saw icicles pointing up right in front of them but luckily, the ice piece they were on broke them as it slid through them. They then flew a little up in the air a few seconds later and they all got off Manny and onto different ice slides. The baby was right next to Sid on the other slide and Sid reached out to him but missed. Sid snapped his fingers in disappointment.

Apparently, the slide that the baby was on, had a limit to it since it showed that it had a curve on it. The baby flew up in the air and everyone watched him. Manny stood up, readying himself to catch the baby. Sid looked ahead and screamed. In front of them was a wall that would end their sliding adventure and right in the front of it was Scrat, trying to get his acorn out of the wall. He tried to pull it out but it didn't do. He turned around to walk off a little ways but screamed when he saw the gang sliding towards him. He quickly turned around and hurriedly tried to pull the acorn out of the wall. Unfortunately…he couldn't…and got hit with Sid as he rammed into the wall, leaving a mark of him on it. Next was Diego. And then Casy. And as Sid and Diego were poking their heads out of Casy's marking on the wall from ramming into it, they saw Manny sliding towards them, his back turned to them. They screamed, which was interrupted by Manny ramming into them and the wall.

Ice spilled all over, which turned into snow, creating a pile all over them. Sid and Manny weren't pile by it but Casy and Diego were and Diego was the first to pop out of it, thrilled by the little adventure.

"Whoo!" he cheered. "Who's up for round two?!" It was then Casy popped up next to Diego, a grin on her face.

"Let's go again!" she cheered as well. "Let's go again!" Diego grinned at her and Casy grinned back but she frowned when Sid just stared at them and when Manny gave them a look. Diego did so as well and cleared his throat, him and Casy stuttering.

"I…Um…uh…just…"

"Just…tell the kid to be more careful…"

Scrat, meanwhile, popped up from the snow pile. He pushed the snow off his eyes and looked around for the acorn. He suddenly cheered up and pranced his way to the right, thinking that's were his acorn way, but instead ran into a wall with an acorn drawn on it. He whined.

Finally after walking their through the icy cave, the gang managed to get out of that part into a less-icier part of the cave. All around them were drawings on the walls. Left to right, even up the walls were drawings. Casy was in front of Manny, Sid, and Diego while they were walking side by side, looking around the cave.

"Whoa…" Sid whispered in amazement when they came across a different area in the cave. Everywhere there were drawings and the gang couldn't but just stare at it in awe. Sid waddled towards a drawing of a saber biting down on antelope. The baby, obliviously afraid of it, buried his head in Sid's neck. "No, it's okay. It's okay." The baby turned his head back at the drawing. "Look, the tigers are just playing tag with the antelope…" Sid paused for a moment to look at the drawing and he became nervous at what he realized what the saber was doing. "…with their teeth." It was then Diego came up to Sid, walking around him hauntingly.

"Come on, Sid," he said. "Let's play tag. You're it." Sid chuckled nervously while Casy just shook her head.

"He's only kidding," Casy assured him when Diego was by Manny's side. Sid smiled at her, as if telling her thanks. Casy walked with Manny, leaving Sid to walk on the other side of the wall.

"Okay, okay, okay," Sid said, his eyes searching on the wall. "Where are the sloth's? You never see any sloths. Have you ever noticed?" Sid then noticed something on the wall that made him happy. He pointed it repeatedly. "Look, Manny! A mammoth!"

"Oh somebody pinch me," Manny said sarcastically. Casy shook her head and mumbled to herself. He seriously didn't had to be so moody. Then again…it was just a drawing…

"That one looks just like you!" Sid said, setting down the baby. Diego walked up behind him and looked at the drawings. Casy was next to follow Diego's suit as Sid continued. "And he's got a family. And he's happy. Look, he's playing with his kid. See? That's your problem." Diego nudged Casy and she looked at him. He motioned towards Manny and Casy looked at him, frowning upon seeing his sadden face. Casy looked at Sid and tried to stop him.

"That's what mammoths are supposed to do."

"Sid…"

"Find a she-mammoth, have baby mammoths…"

"Sid!" Diego barked, making the sloth jumped. He turned towards Diego.

"What?" he asked.

"Shut up," Casy told him. Sid looked confused than ever.

"But..but…" Sid's attention turned to Manny and he stopped stuttering. "Oh…" Manny was quiet for a long moment. Casy and Diego looked at each other sadly. Manny pulled his trunk towards the painting he was looking at and touched it, as if recalling a memory. As he moved his trunk across the drawing, the baby's hand slide up on it, Manny's trunk touching the baby's hand. He looked down at the baby, finding him standing up, though bent over a little. He tumbled forwards and if it wasn't for Manny putting his trunk in front of him, he would've fallen. Manny wrapped his trunk around the baby and lifted him up and stared at the baby. Unexpected, the baby hugged the tusk and Manny pulled the baby to him, closing his eyes. Sid, who had wiped a tear from his eye, wiped his finger on Casy's fur, who looked at him in disgust.

"Oh Sid!" Casy yelled, looking down where Sid had wiped. Diego just laughed while Sid just looked at her sheepishly. Manny pulled away from the baby and put him on his head, starting to walk off. Sid clasped his hands together happily, earning odd looks from Diego, who frowned and waddled-run his way to follow Manny. Casy looked at Diego and shook her head, letting out a small sigh from her lips. She began to follow Sid and Diego stared at the drawing sadly for a moment before following Casy slowly.
