There's no title card this time. Basket and pulse2010, the purple Cave Prospectors, pick up underground where Episode 4 left them, next to a cave that was blocked off earlier. "This might actually go somewhere." A zombie is waiting right there.
Following the lava
The cave links up with another one, and a lava flow runs through it. "This lava keeps on going." "Yep, that's what lava does." The tunnel stays narrow and keeps going without opening into the kind of huge cavern one of them would love to see. "This isn't going anywhere. I mean, it's going somewhere, but it's not going anywhere."
The Tab list shows the other teams having a rough time. TopStiGear is down to a heart and a half. Steel_Douglas drops from almost full to two and a half hearts within a few minutes. "It does appear that they're having their own problems."
The border question
Chat gets busy. TopStiGear asks "where is everyone?" and Steel_Douglas answers "at the pool." Then TopStiGear asks what the world border goes down to. Basket explains in chat that it only shrinks to 200 by 200 if deaths are the only thing shrinking it and two people are left, "but since we have an auto shrink each sundown if it's not shrinking," it could go all the way to zero.
Right on cue, "Soul Crusher will wake in 2 minutes!" Steel_Douglas types "i dont like that." Then come the red lines, "Soul Crusher is coming!" and "The World Border is shrinking 300 blocks over 5 minutes." No death line comes before it. TopStiGear asks what it started at, and Basket answers "2000x2000."
Bows, boats and a team name
Every passage turns out to be a dead end, and the diamonds still haven't shown up. "We should just give up on those diamonds because we already mined everything." The new plan is bows and boats. Basket crafts a bow, then a boat. Inventories are full, and one of them is carrying about four stacks of cobblestone, far more than anyone needs. The team name comes up on voice too, and it stays Cave Prospectors.
Food is getting thin. One of them is down to a single pork chop.
Midnight on the ice
They dig up toward spawn. "The hard part is it's amplified." Then, suddenly: "No, we're at the surface!" It's midnight, and the boat idea falls apart fast. The water above is capped with ice, and one boat ends up somewhere overhead where nobody can see it. "Even if we did go up there, there's so much ice right now." Sand gets picked up near the top, maybe for TNT, along with gunpowder one of them had been throwing away.
"I see the border over there." After so long in the caves, the open surface is unsettling. "My heart is racing." Swimming across the open water turns out to be fast, at least.
Feathers at sunrise
The sun comes up and they find chickens on the ice. The feathers are for arrows. "I got four feathers. Awesome." Someone also notices the breathing helmet isn't on. A furnace and a crafting table go down on the ice to cook pork chops and chicken.
In chat, TopStiGear asks "has anyone found spawn yet?" Basket answers "maybe," and erynfaith types "UMMM DON'T KNOW." There may not be any apple trees around here. "I have six arrows."
The server posts "End of Day 5. Players remaining:" with erynfaith, OjiiOtousan, Steel_Douglas, TopStiGear, pulse2010 and BasketMC. Basket is alive on the ice with pulse2010, and the end credits follow.
