do you have video of this or could you recreate this

can you upload the video to youtube and link it here

i have no idea what this post's glitch was, but something i found was a bossfight softlock. basically you do normal boss phase 1 skip but take damage on the third hit (hit early) and he'll go to the other side. after hitting him, he goes from the right to the left and red ball gets stuck because of the borders on the boss. literal wall to red ball.
