Episode 4 starts where the third one left off, underground and still looking for a way out of a cave that has run dry. It is dark on the surface, though nobody is quite sure what time it is. Basket, Scoti_Garbidis and PsychoSFK want two things they cannot get down here: string for a bow, and chickens for arrows.
Diamonds for someone else
Chat keeps reporting other teams' luck. sneegsnag earns the DIAMONDS! achievement, someone replies "hax", and kanivatimber answers, "I gave them to him!" Back in the cave, the team is still on gold. There is enough for another golden apple, and the levels are adding up too. Basket's bar reads 16.
Later fuubi earns three achievements in a row, and BasketMC types "congrats" in chat. The Tab list shows the whole server, and all three members of GopherCraft are at full health. RanquestLP and dolinmyster are still grayed out, and no new names have joined them.
A spawner in the cobblestone
Looking for a new way up, they break into a small cobblestone room with a spawner in the middle and chests along the walls. It is a spider spawner. "We're all getting bows." Then one of them spots an endermite inside and tells the others to back up. Basket pours a lava bucket into the room to clear it out before anyone steps in.
The chests hold redstone, a name tag, horse armor, string and gunpowder, and Basket takes the gunpowder. The plan is to let the spawner make spiders and farm them for string through a one-block gap. One spider drops a single string. "We need two more string."
Executive decision
Basket steps away from the keyboard for a moment, and the screen sits still facing the spawner. When Basket gets back, the teammates explain what happened: they broke it. "Executive decision." Nobody wanted to keep waiting on jumpy spiders. By the time the team reaches the surface, Basket has a bow on the hotbar, with almost no arrows to shoot from it.
Up to the plains
With the cave tapped out, they dig up to the surface. It is daytime, and a wide grassy plain spreads out in front of them, with a river and a mountain off to one side. There are cows, sheep and a donkey, and some sugar cane gets picked up, but no chickens anywhere.
The open ground makes the team nervous. "Since we don't have a lot of arrows we're at a disadvantage on this open plains." There is a short talk about a pincer move if they meet another team. "There are no mobs here at all, actually, which is kind of disconcerting. We might be near somebody." Nobody shows up.
Back underground for the night
As the sun goes down, they find a steep cave entrance and head in, past a zombie, and cap the opening behind them. Inside it splits into two paths. One loops back to a little lava, and the other shows iron. DarthTimmanis posts "80 Minute Marker" in chat. The episode ends with all three alive in the new cave, still without a chicken.
