00:00Today, I am surviving 99 nights in the forest to save my brain rot because it was last seen
00:07in the woods with Kato. So I'm going to do everything I can to save them both. Guys,
00:13I hired a real bounty hunter in order to help us find Kato. Don't worry, we'll find him.
00:19Why am I here? You promised me that we would go to McDonald's. That was the only way I could get
00:23you to come. All right, guys, come on. Wait, look, guys, it's Kato's phone. How do you know it's his
00:31phone? Let me go to the camera roll. I guarantee you it'll be obvious. Yep, look at all the aura
00:37farming. I knew this was his. Get down. Oh my gosh, guys, those are cultists. I bet they're the
00:44ones who took Kato. I got this. Wait, wait, what? Mike, Mike, where are you going?
00:53Oh, all right. Yo, Mike needs our help. Come on, let's go. Hey.
01:00Yo, stop. Yo, chill, bro. Chill, chill, chill.
01:11Hey.
01:14Oh, yo, good shot. Got you, buddy. All right, guys, come on. Let's grab the book.
01:22Time for them to answer some questions. All right, guys, tell us what this book does.
01:29I'm not saying anything. Wait, what? You just did say something.
01:34Stupid. All right, fine. If you guys don't want to talk, I guess we're just going to have
01:38to start reading the book. No, don't. Don't read the book. It has powers. Wait, what do you
01:43mean it has powers? Yo, guys, check this out. There's literally pictures of missing kids right
01:50here. That's perfect. We can use the book to find Kato. Yo, this forest is really creepy,
01:54and I guess he's not in here, bro. Let's head out. I think that way is out. Come on. Guys,
01:59not only is this forest creepy, but it's also huge. So we need to get out of here as fast
02:05as we can to not waste any time. All right, guys, we just made it out of the forest.
02:12Wait, what's a cop doing here? Yo, yo, is everything okay, officer? You're all under arrest.
02:17There are four missing kids, and they were last seen in the woods, which you happen to
02:21be in. That sucks. Wait, but no, we were looking for a missing kid also. Whatever. Everyone's
02:26going to jail. Wait, what? Oh, no, no, no, no. Oh, no, this is not good for us. If we can't get out
02:32of jail, we will never be able to save Kato and my brain rot. We need to try and convince the police
02:37officer we were trying to help. Officer, please. I literally have evidence that proves we didn't do
02:43anything. Well, you're all still going to jail, so tell it to the judge. Guys, what are we supposed
02:50to do? We need to figure out a way out of here. Wait, I have an idea. What if we start a big fight?
02:56Then the officer will have to open the cell, and then we can just escape. What are you talking
03:00about? I got one day till I get out of here. Hey there. Excuse me, sweetheart.
03:07How about now?
03:20I'm an artist. You are my master, baby.
03:26I'm sorry, officer, but we have to go save Kato now. Let's go. Wait, you're already in the police
03:40scanner. You're not going to get away with this. Guys, that's it. If we can use the police's high-tech
03:45security, we'll be able to decode this book, and that'll help us find Kato. Let's go. Wait a second.
03:51You guys are trying to find Kato? Why didn't you tell me that? We did. Get out. All right,
03:57you know what, officer? If we let you out of there, can we please use your technology to
04:02help us read this book? Of course. All right, let's go do that.
04:05All right, officer, start scanning right here. Okay, the book's scanning. How long's it going
04:19to take? Six, seven seconds. All right, come on, hurry. Wait, look, there's an address. That's
04:26probably where they're keeping Kato and the other missing kids. It says they're in the middle
04:30of the woods. That makes sense. That's where the cultist lives. We should go. Let's go. Wait,
04:36officer, are you going to come with us? You know what? I'll stay here. The book's still scanning,
04:39and I'll look for more clues. Wait, what if I sit with the computer and look for clues? I hate the
04:44boards. It's really scary. Does that work with you? Let's do it. Let's move. All right,
04:48but shutters, you have to stay focused here, okay? You got it. All right, lock in. Come on,
04:52guys. And now that we have a real police officer helping us, hopefully we can find Kato and my brain
04:58rod faster. All right, guys, this is the address, and look, there's four cultists right there. This
05:03has to be the place. Mike Ferguson's got this. No, there's hundreds of cultists. If we take them
05:08out, they'll alert the others, and we'll all be in trouble. We need to sneak in without making a
05:13sound. Listen, you're already way more helpful than shutters. Okay, guys, let's go around.
05:19Yo, snake, snake, snake. Oh, I hate snakes. You know what, guys? This snake is actually giving me an idea.
05:24Come here, buddy. Come on. Come here. All right, guys. Come on. I got him. Follow me this way.
05:30All right, you guys remember the plan? I hope this works. Let's go.
05:39Oh, hi there. Private property. What do you want? We're animal control. We're here to help with the
05:46snake infestation. King didn't say anything about snakes. Get them. Wait, wait, wait. Hold on. Hold on.
05:50Oh, look. There's a snake right there. Oh, my gosh. I hate snakes. Here. Yeah. Come on.
05:56Get in there. Go. All right. Come on, boys. We're going to clear the area. We're going to go make
06:00sure there's no other snakes inside. Come on. Let's go. Guys, look. One of the missing
06:06kids is right there. Oh, save it, kid. Wait. It's locked. The key is in that bucket of roaches.
06:15Wait. What? Oh, uh, that kid looks happy in there, right? Yeah. No, no, no. Guys,
06:20stop. We have to save this kid. Wait. I thought a police officer was supposed to be super brave,
06:26and I thought bounty hunters weren't afraid of anything. Well, some things I am afraid of.
06:30Hey, cockroaches. Creep me out. All right. Fine. I'll do it. Don't worry. Don't worry,
06:35dino kid. I got you. Oh, gosh, guys. There's so many roaches in there. Oh, gosh. They're crawling
06:44all over my hand. I got to make this fast. Okay. Okay. Okay. I got the key. I got the key.
06:52Come on out, dino kid. Please. There's another kid in the next room. You should save him next.
06:58Wait, guys. That must be Kato. Okay. Sounds good. Just head for that way over there,
07:02and you should be safe. Okay? Okay. All right. See you later. Come on, guys. Let's go, guys.
07:10Guys, he's guarding a room. He has to be hiding something. Wait. I have an idea.
07:17Time to distract him.
07:18What was that?
07:26Wait, guys. Come over here.
07:28Look. There's Kraken Kid. We got to go save him. Hold on a second. Those are two military-grade
07:33human glue traps. Step aside. I'm the world's best police officer.
