Sky Plays 1.3 is a collection of failures and discoveries from his first attempt at the 1.3 update. At one point, he enters a desert village house and says "Father, forgive me, for I have sinned" to the villager inside. Then he proceeds to STEAL THE TABLE.
While this is happening, deadlox was shot by a skeleton off-screen, revealed by the chat-log
At about 12 minutes in, Ty is building a snowblock tower, before Sky hits him with a snowball with huge knockback (called "Trollface"). Ty dies by falling, and after Sky tells him he can't cheat, Ty smacks his head on his desk, trying very hard not to laugh, and Sky loses it.
Nega-Squid. Especially Sky's "Really? This is actually happening?" attitude throughout the scene.
From the 10th Cops and Robbers 2.0, Ssundee, who appears to have gone mentally unstable as he hates Sky yet sees him as a friend, and is obsessed with cake.
Ssundee: Do you know what I had to do to make this cake? Do you know what I had to do?
At one point, Ssundee places a cake in front of the Dead Cell door. Later in that round...
Sky: I can't get out, there's a cake in my way!
Explosions were turned off for both rounds during the video, but mobs were not. Jerome found a Creeper in each round. Think about it.
SHORTEST SURVIVAL GAMES EVER has Sky singing a song about butter, which he created himself. Hilariously, he rounds the corner to find CaptainSparklez and FLIPS OUT, bringing the song to a screeching halt.
Sky: All I need is Budder to build up my castle- WOAH OH SHIT
cuts to another scene when BajanCanadian has returned
Sky (still singing): Mitch is back! Mitch is back! Mitch is back! Mitch is back!
Cops and Robbers: Watermelon Massacre, which was pretty much inevitable due to Bashur being the warden. BajanCanadian takes advantage of this by placing melons (which he and Bashur refer to as Bashur's children) everywhere. Sky, xRpMx13, and BajanCanadian spent the rest of the episode trying to escape from the prison as Bashur tries to stop them. And this involves a lot of melons.
BajanCanadian (who has filled the hallway with watermelons): Mr. Security Guard! If you want to get over here, you're going to have to kill your own kind!
A rather notable example: Bashur somehow getting stuck underneath the prison, which is referred to as "Hell". (Luckily, he managed to make it back out.)
A very confused Fluffy (who was the first to escape and thus was not involved for most of the video) listens in to the others' conversations while he builds a house outside the prison.
Plus, the final nail in this bizarre coffin? Sky's out-of-the-blue Bob Ross reference.
