The Speedy-Strange-Funky-Thingy Horse Problem

I was playing in my Minecraft world with my friend and then while my friend was riding her horse, it fell in the water on my bridge and it took a while to get it out. When she got it out, she parked it in front of her house then I only mounted it for absolutely no reason. Then, it started drifting on it's side towards the area where her horse got stuck. I have no idea why this happened.

 

P.S. Dear Mojang,

can you give a few extra days to get the 15th anniversary cape because I'm so desperate to get it and I think I was sadly a bit too late. Please add like a few more days starting from 2024 August 3 Saturday until 2024 August 11 Sunday. 🥺

Me, my friends, and my brother really want it
