Subplot:

Scrat was excited.

He couldn't wait to see the look on Scratte's face when he returned the acorn to her. He had finally got the acorn half back from Skrit and had finally made it into the small treehouse where he and Scratte lived. There was a problem though.

Scrat saw the look of Scratte's stomach. It looked round. Scrat didn't know what he was in for.

When Scratte saw Scrat with her acorn half, she ran up to him and hugged him. Scrat hugged here excitedly back when she gave him a gesture like "shh, shh, you'll wake up the twins. Then she pointed to the size of her stomach. Scrat could see Scratte, the love of his life, was pregnant with twins.

Scrat couldn't be happier. First he was fine chasing his precious acorn but then having a family made him happier.

Scrat knew what to do. He grabbed his acorn half and swung off back into the dinosaur world to find another acorn where Skrit, his rival over Scratte's love still remained.

Plot:

"This way, mammoths!"

Buck led the herd through the dinosaur world. He was going to lead them home. He wasn't yet ready to consider joining the herd and unlike his father: Avery.

"Doesn't look like a jungle of misery anymore," said Crash. Eddie totally agreed.

Avery looked at his son. "Buck," he asked, "are you sure you know where you are going?"

The one-eyed weasel laughed. "I've been living down here for battling it out with Rudy. I know exactly where I'm going."

Peaches walked alongside her dad: Manny. Crash and Eddie were on Ellie's tusks like they always were. Sid and Diego were at the back while Buck and Avery led the way.

"Ah, too bad Buck's not joining the herd, huh?" sighed Sid. Diego agreed. "Um, yeah. And so isn't Avery." "Yeah!" Sid sighed, "Without them, the herd wouldn't be that fun anymore."

Buck heard this and so did Avery. "Buck," said Avery, "Why won't you join the herd?" "Well," said Buck, thinking of what Sid said, "I don't know, dad. I mean…I lived down here so long battling it out with Rudy, I don't think I should leave here."

Sid and Diego, hearing this, frowned.

Sid was facing a bigger conflict: missing his family. He thought about the times he had together with the dinosaur kids, bathing them, playing hide and seek with them and when they got all over him and bit him. Then he remembered Momma bowing him over defeating Rudy and the way the kids looked as eggs. Sid, having a tear struck down his eye, frowned.

"Hey, Sid," called Manny, "keep up there, will ya?" Ellie looked at Manny and exclaimed: "Manny, I think there's something bothering Sid. Why don't you talk to him? Just like you did with Diego and Peaches."

Manny walked to Sid. "Um, hey Sid." "Oh, hey Manny" Sid replied.

Manny gulped. "Look, Ellie said there was something bothering you. So she told me to go and talk and…" "Actually, there is something bothering me, Manny," interrupted Sid, "and it's kinda uncomfortable to explain." "Ok," said Manny, "then I'll just tell Ellie there's nothing bothering you."

Sid sighed. "Wait, Manny!" he called. "Yes Sid," said Manny.

"Look, I just can't do this anymore. Every night I can't sleep. Ever since I've came back to this world, I've been starting to miss Momma and the kids. I mean I dream about them every night and I just miss being a parent, Manny."

"So, does this mean you're jealous of me having a family?" asked Manny. "No, no, no! Manny, it's nothing like that?" "No, it's okay, Sid," interrupted Manny, "go. Find your family. Out there in the jungle. Don't come screaming to me when you get eaten. Like you can even take care of yourself."

"Wait, Manny. It's nothing like that," called Sid after him. "Bye, Sid," Manny replied. "What's going on?" questioned Ellie. "Sid's jealous," Manny replied, "of me and you and of Peaches. I told him to go find his own family. I don't want him here anymore. Hope the subject of his jealousy won't kick him on the butt on the way out" and looked at Peaches.

"Wait, dad," said Peaches, 'I don't want Sid to leave." Ellie looked sadly back at Sid as he trundled along the pathway to Lava Falls by himself. "Now that's a lot of aloneness," said Manny as he watched his old friend walk to Lava Falls.

Ellie shot Manny a disappointed look and so did Peaches. Crash and Eddie barely even looked at him and Diego trudged by without saying a word. Manny felt sad and alone now that no one was talking to him. Sid walked along up to the pathway to Lava Falls, feeling worse then Manny.
