With Howdy, Dexter, Pashmina, and Penelope...

"I wonder where they could be," Howdy muttered. "I saw them near the merry-go-round," Pashmina acknowledged. "Ookyoo!" Penelope shouted. "We'll check there," Dexter said.
The foursome dashed to the merry-go-round. "This place looks deserted!" Howdy shouted. "How would we find anyone here?" "Check the hills for passageways," Dexter told him. "I'm glad we have a really smart Ham-Ham with us," Pashmina said. "I'm smart!" Howdy shouted. "Sure you are," she lied.
"I don't think this is doing any good," Howdy said after ten minutes. "Ookyoo!" Penelope shouted when a breeze came. "Penelope, what did you sense?" Pashmina shouted above the breeze. Penelope took off running down the river with the three Ham-Hams following her.
Penelope ran downriver. Soon, Pashmina, Howdy, and Dexter fell behind her and couldn't catch up. There was a big rock in the middle of the river where they stopped. Penelope climbed the big, shady tree and looked down at them. Pashmina looked up at her and saw something in the tree. She screamed, "Penelope!" "What is it, Pashmina?" Howdy and Dexter yelled in unison. "Penelope!" Pashmina screamed again and pointed to where Penelope was. But Penelope wasn't there anymore.
"Something got her!" Pashmina screamed. "It grabbed her around her waist and took Penelope!" "What could do that?" Dexter said. "Don't you see?!" Howdy scolded. "Let's get the Ham-Hams! And I mean pronto!"

With Hamtaro and his gang...

Hamtaro, Caitlin, Bijou, and Oxnard were searching the trees for passageways. "I can't find any!" Oxnard shouted. "I'm aggravated myself," Hamtaro remarked. "I wonder how everyone else is doing," Caitlin mumbled. "`Oui," Bijou replied.
"Hamtaro! Guys!" Pashmina screamed. "What is it?" Hamtaro queried. "Something got Penelope!" Dexter yelled. "What did it look like?" Oxnard asked. "It was up in a tree with Penelope," Pashmina remarked, "and we were down on the ground. It was a big shady tree so the arm appeared black." "Very black?" Howdy asked. "You didn't tell us! That could be a- " "Penelope!!!" Pashmina cried. "I'm sorry! Please forgive me! I let something harm little Penelope!" "Pashmina," Caitlin said, "it wasn't something. It was most likely one of those Bad Hams that got her." "Penelope!" Pashmina cried again. "I am so sorry! I let Penelope down! I let her get hurt!"
The other Ham-Hams heard Pashmina and went to her aid. "A Bad Ham got her?" Jingle inquired. Pashmina started to cry. "Yes," she sniffled. "Don't worry, baby," Stan told her. "We'll get her back. Or I will if no one else is going to help me." Stan walked off and started down the river. "Big shady tree? Rock in the middle of the river? Got it down," Stan said.
Stan found the elegant house that Mike and Stella had asked for directions previously. He knocked on the door. "Hello?" the girl hamster that gave Mike and Stella instructions answered. "Hamha, Ham Beauty," Stan said. "My name's Stan, babylicious. Do you want to go out with me?" "No!" she yelled and slammed the door in his face. "OK, dudette," Stan retorted and walked on down the river.
"There's the tree," he said. Stan climbed up it and looked around. Stan muttered, "I just want to get this over wi-" Before he had finished his words, Stan was knocked out cold.
