They're still in the Helician Labs jungle, where the Predators hide in the trees, and the counter reads Scoti 78, Basket 73. Despite the title, both of them are here for almost all of it. The diamonds and TNT from last time are still sitting down below, and they're still leaving them alone.
The bridge show
One of them hangs back to pick off spawners and "call in airstrikes" while the other builds across the gap. "Hey guys, welcome back to the bridge show. I'm making a fancy bridge though. I'm using quartz pillars."
On the far side there's a glass case with red blocks around it. "Guess what is in here." "A key? No, I give up." There's no crystal in it, and they start wondering whether the Shadow Keys are for the end boss. Basket has a Titanium Pickaxe out regardless. "I'm telling you, dude, I think we're about to get tricked."
While Scoti's away
Down below are bow guys they can't reach, so Basket pours a lava bucket on them instead. Iron is running low ("How much iron do you have?" "None."), so burning a few mobs might help with that too.
Then Scoti steps away for a minute, and that's the title. Basket gets the Arcane Bombs out. By the time Scoti is back, a good part of the jungle floor is on fire. "Welcome back. So I blew up some stuff." Including, almost, a chest.
"We'll get it now"
One of them wants to leave the chest for later, since there are charged creepers spawning right behind it. "We'll get it now." "I'd rather wait until there's not charged creepers there." Scoti goes down into the water to grab it and comes straight back up, because there are Predators around. The haul is "a diamond helmet, a diamond sword, a gold sword that's Sharpness 10, Unbreaking 3," mechanical boots with Protection III and Blast Protection II, and a splash potion of invisibility. A Predator spawner in a tree comes out on the way back, and the loot goes into the chest.
Stairs into the ground
Past a wall that they figure leads to another reward room, Predators start dropping out of the trees. "Next to you, behind you, right around your face." A staircase goes down into the ground, ringed by more spawners in the trees. Basket throws a Lightning Trap down there. "That one's a lightning trap. I guess it's not a very big range." An invisible baby zombie shows up when it catches fire.
Down the hole
They pour water down the hole, and Scoti jumps in first to look around while Basket shoots the mobs falling in from above. Down there is a fence gate, and a lot of mobs headed Scoti's way. "This feels like a trap." Basket follows Scoti down, they open up a bigger area, and they find a chest. Nobody touches it yet. They keep the water flowing in case there's TNT. "We don't need to even go in there. It's just the chest that's the target."
"This is a long episode, man." So they leave the chest for next time. Nobody dies in this one; the counter ends at Scoti 78, Basket 73. The monument isn't shown, so the emerald blocks stay at 8 of 12.
