I'd like to thank Jay'swhisper (u/4042768) for reading every single chapter. Here's what happens when the gang visits Russ T! Let's-a Go!

"So," started the Wise Toad, "What do you want to know?"

Mario asked as he sat on a chair in front of Russ, "Do you have any idea where the rainbow-colored blobs came from, and how they got here?"

"Ah, the usual advice like back then in 2001?" Russ replied. "Well, I've been reading books about things in other worlds, like the green-clad hero with a sword and a woman in a mechanical suit, and I recall reading about something that looks like those blobs that rained above my house. Some were running up and down the streets, but it didn't do any damage to the houses or anything."

Mario leaned forward on the desk towards Russ T. The toad continued, "Anyway, if I knew what it was called, I'd look it up in the book. Let me see..." Russ T. looked through his massive bookshelves, alphabetically aligned, but after a minute or so, he paused, sighed, and sat down on his desk again.

"I'm sorry I don't have it," Russ T sighed. "I just remembered Professor Kolorado came this morning and borrowed it. I said 'no' about five or six times before, but he seemed to really want the book. I think I won't get it back until next week-or next month because he's Kolorado-and I don't think I'll be able to answer anything related to the blobs and its world."

Mario thanked the Wise Toad, and went out of Russ T's house. The Three Visitors were waiting outside the house for Mario to finish asking his question. Ringo was wondering how the space-warp occurred, Arle was wondering where Carbuncle is, and Amitie was wondering if she would see her friends again.

Mario addressed the Visitors, "Russ T.'s book was borrowed by a professor in another town. I'm afraid we can't get any information from Russ T. without his only book that has information from other worlds."

The Visitors sighed. Right when they sighed, the MailBox SP rang. Mario opened it. It said:

~~~~~~
Sender: Luigi

Subject: Hey bro!
Hey, Mario! I just googled the three girls' names and I found the Wikipedia page for the universe the Visitors and the blobs came from. It says that in that world, the inhabitants play games with the blobs to settle arguments or to play with each other. It also said there are half-onion half-pixy creatures and frogs that live in acorn caps. How interesting! Some inhabitants of other worlds can come to the world whenever there's a space warp, and that happens randomly, once or twice in a year.
So in my opinion, whenever we find that Princess Peach in missing, Bowser's at it again. So why don't you go to Bowser's keep and beat him up like usual? ;) Bye!
Good luck,
Luigi

Mario closed the MailBox SP. The Visitors read it too.

Amitie started, "So, why not do what your green brother suggested to do?"

"Agreed," said Ringo.

Mario picked up his hammer and said, "Let's-a Go!"

So, I hope you liked the 4th chapter of Mario Meets Puyo! If you have any ideas or want this to continue (both is really appreciated), please make a review. If I get a review, I'll write a chapter. If I get 2 (from different people), I'll write two, and so on. It's summer vacation now, so I have too much extra time, not counting my new rollerblades. Thank you so much!
