Presenting: The Orange! You get one every time you enter your world. But be careful to not eat them in the wrong hand...
The potential consequences are as follows if you do:
1 in 100 chance to just straight up kill you
Your health gets randomized if you have stripped acacia wood ANYWHERE in your inventory
Turn poison into regeneration (and vice versa)
Set you on fire for 1 hour if you're within 16 blocks of a cow
If you're at Y = 126, you get teleported into the void
If you're in the swim/crawl pose, an ender pearl is launched in a random direction
Spawns a creeper if you're standing on coarse dirt
If you're sneaking, you get launched very high up
Gives you levitation 50 for 5 seconds if you're in a sparse jungle
If you have exactly 46 levels, an anvil gets summoned on your head
If you're holding a certain "Danger Item", Orange 47 will find you. He doesn't appreciate you holding nothing, either.
Pushes you backwards if you're moving
Pushes you upwards if you're falling
Pushes you downwards if you're ascending
If you have the mod "Born in Chaos" installed, it launches a fireball onto your head
Switches your x and z coordinates then teleports you to the surface if you're in a dripstone cave
If your FOV is set to 63, you instantly crash
1 in 1,000,000 chance you'll get an achievement and a ton of xp
These activate in the order listed, starting from the top and ending at the bottom. Have fun!
Oh and oranges are actually decent food sources, providing 2 hunger and 10 saturation.
