Literally just a bonus room

Another one screen pit puzzle that heavily relies on the stun glitch. This time, it also abuses null sprite spitting to manipulate the properties of the sprite in slot #1. Not particularly hard if you have experience with stun setups but still fun.
I tried a bit to get the normal exit but I couldn't figure out how to set the stun timer of the key or how to stun the keyhole (both of these would give a sliding blue koopa, which gives a koopa kid)... maybe it's impossible (though in this game, you never know)
