**Summary:**
This article/video highlights unusual and broken features from various Minecraft snapshots (development versions). Key points include:
1. **Vindicators without axes** (18w40a): Initially, vindicators in Raider Mansions didn't have axes, making them less threatening.
2. **Useless Green Villagers** (pre-1.9): These villagers couldn't trade until a brief period in snapshot 16w33a when they could be given a profession under specific conditions.
3. **Flying Striders** (20w17a): A glitch allowed Striders to be mounted in mid-air, enabling flying in Survival mode.
4. **Overpowered Raider Captain Effect** (20w17a): Killing multiple captains could grant an excessively powerful "Bad Omen" effect (up to level 6).
5. **Broken Enchantments** (1.16 Playlist #6): Killing Piglins in Bastions could yield items with all possible enchantments, including incompatible ones.
6. **Giant End Islands** (21w13a): The End's island generation was briefly broken, creating massive islands.
7. **Glowstone Block Exploit** (21w03a): Placing Glowstone in the Nether could generate water and obsidian for free.
8. **Rare "Yoki Villager"** (1.16.2 #1): A zombified villager mounted on a chicken could be cured to create a unique "Yoki Villager" in Survival mode.
