Here are the key facts extracted from the text:
1. To achieve super fast speed in Minecraft, you need an elytra, a pair of boots with Depth Strider III and Soul Speed III, and dolphins.
2. To use this trick, you need to put a dolphin above soul sand to keep it alive, and then water on top of slabs.
3. Activating your elytra, holding down control, and getting dolphin's grace allows you to move at high speed.
4. The speed trick lasts for 7 seconds, but it can be extended indefinitely by topping up the system with regular dolphins.
5. Turtles drop a bowl when they're killed by lightning.
6. The bowl is made of wood.
7. To get a lot of animation particles, you can put XP on top of redstone ore.
8. The effect of the animation particles increases with the amount of XP used.
9. The XP won't last forever, and the effect is lost when it comes off the redstone ore.
10. It's possible to crawl into a one-high space in Minecraft.
11. You can't go into a half-block high space even if you try to crawl in.
12. However, you can fly in between two beds, making it possible to create a sort of bunk bed.

14. You can put thorns armor on villagers and allays, and if you punch them, you can die.

22. There is a killer bunny in Minecraft that can hurt players.
23. Renaming a bunny to "Toast" changes its appearance, but not its behavior.
