why are there character heads at the bottom of the loading screen
Good question @Gabe_N! The characters actually used to pop up during the loading screen and it looked like the picture below on the right:
The one on the left was a replica of the loading screen that I made with Utensil Mouth and LunaMorgana387 and you can see the project here if you like, to see what it sort of looked like when the characters popped up.
Hopscotch changed it at some point and made the characters hide at the bottom. I have no idea why they changed it but I'm curious too
