The gang sat down at a group of tables and began working.

"I think I've got it!" Melody shouted happily.

"Oh boy," Alexandra groaned. "This I've got to hear!"

"Let's hear it, Melody," Alan said.

"Jeremiah was a bullfrog!" Melody shouted, giggling.

"You've got to be kidding me!" Alexandra yelled. "Jeremiah was a bullfrog?! That can't possibly be it!"

"Well, that's what I got," Valerie said.

"Me too," Alan said.

"And me," Josie replied. "And if I know my Three Dog Night, Jeremiah was a bullfrog was the first line in their song Joy to the World."

"I thought that was a Christmas song," Melody said.

"It is," Valerie said. "But Three Dog Night's Joy to the World was different. Now, what do we look for?"

"A bullfrog named Jeremiah?" Melody suggested.

"Oh Melody, be serious!" Alexandra shouted.

"Well, it's a start anyway," Alan said.

"You mean we're actually going to look for a frog named Jeremiah?!" Alexandra shouted, incredulously.

"Why not?" Josie said, shrugging. "It's the only lead we have so far."

"Hey, maybe we should call Robert," Melody said. "He knows lots of people. Maybe he knows a bullfrog named Jeremiah!"

Melody grabbed the phone from Alan and began dialing. Robert picked it up after about two rings.

"Hi, Robert," Melody said. "It's me, Melody! Listen, we were wondering, since you know people, do you know a bullfrog named Jeremiah?"

"A bullfrog named what?!" Robert shouted into the phone. "Did you just say a bullfrog named Jeremiah?"

"Yeah. Our last clue was Jeremiah was a bullfrog."

"You're kidding, right?"

"No, really."

"Okay, give me a minute."

Robert paused, and thought this over. He ran through the song "Joy to the World" in his head, but he couldn't come up with anything. He finally figured it out and picked up his phone.

"Still there, Mel?" he asked.

"Yeah, I'm still here," Melody said.

"Okay, I thought about this, and there's this miniature golf course at the edge of town. My sister goes there frequently, and she has told me at the eighteenth hole, you putt the ball into the mouth of this huge frog. The locals nicknamed the frog Jeremiah."

"Great! Thanks, Robert! Bye!"

Melody hung up and gave the phone back to Alan.

"Robert said that there's a miniature golf course with a bullfrog named Jeremiah!" she shouted.

"Well, then, let's go," Alan said.

The gang made it to the golf course in record time. It was practically deserted. That was a good thing. Then no one would notice what they were doing. They went to the eighteenth hole, and there was the biggest green frog any of them had ever seen, with the biggest mouth any of them had ever seen as well!

"Holey moley," Alan said.

"That's got to be Jeremiah," Valerie said. "Let's start looking."

Valerie got down on the ground and tried to go into the mouth, but she didn't get very far before she got stuck. She pulled herself out and groaned.

"This frog may have a big mouth," she said. "But it's not big enough."

"Maybe not for you," Alexandra said, holding up her cat. "But here's someone that can go in and get our clue."

Alexandra put Sebastian down, and the cat ran inside the frog's mouth. He looked around, until he spotted something up on a corner. He scaled the wall, grabbed the card, and ran out of the mouth.

"Good work, Sebastian," Alan said, taking the card. Then he sighed. "Here we go again."

79464 66 2 7827

"There has got to be an easier way to do this," Alexandra said.

"So far, it doesn't look like it," Josie said with a sigh.

The others had to agree with that, and they went to work translating. Finally, Alexandra got something.

"What I've got is swing on a star," Alexandra said.

"Oh brother, another weird message," Valerie groaned.

"I wonder what this one means," Josie said.

"That's simple, Josiekins," Alexandra said. "I'll bet it's a planetarium."

"What makes you say that, Alexandra?" Alan asked.

"The only other place it could be is a playground," Alexandra said. "And we were just at a playground, and the clue we found there led us to the bullfrog."

"She's got a point," Valerie said. "Come on, guys. We'd better get moving."

"Yeah," Josie said. "The sooner we find the next clue, the sooner we find Alex."

"I hope he's all right," Melody said, worried. "Golly, I'd hate to think what the Mastermind's going to do if we run out of time!"

"How much time do we have, anyway?" Alexandra asked.

"I don't know," Alan said. "All the note said was that we didn't have much time. The Mastermind didn't say exactly how much time we did have."

"Then we'd better speed up the search," Valerie said.

The others nodded and hit the planetarium. Unfortunately, there was a sign on the door that said "Closed Sundays." But now was not the time to pay attention to signs like that.

"How do we get in?" Melody asked.

"Do your thing, Sebastian," Valerie said, picking up the cat, and holding him up to the lock on the door. Sebastian bared a claw, and began picking at the lock until the door opened.

"Way to go, Sebastian," Josie said. "You're definitely better than any lock pick!"

Josie and the gang walked inside the planetarium, and began looking around. They had to do this quickly, just in case a security guard was around. After several minutes of searching, Melody grabbed an index card off a projector. She looked at it, and then called to the others.

"Hey guys!" she shouted. "I've found the next clue!"

"Good work, Melody," Alan said, taking the card. He looked at it and sighed.

"Don't tell me," Alexandra said. "Another set of numbers."

"I'm afraid so," Alan replied.

277537 7322437 2262627 263 73277

"All these numbers are starting to give me a headache!" Alexandra shouted.

"Unfortunately, this is the only way to find the Mastermind," Valerie said.

"Gee, maybe we should try calling that psychic hotline Robert was talking about earlier," Melody said.

"Never mind, Melody," Josie said. "Let's just get to work finding out what this one means."
