I have an idea for the fizzer and it’s room and that idea is dimensional collision basically the fizzer will get unstable cause no one is monitoring and cause a rift in reality and that rift will take you to a weird grounded yard and your buggies will come and you could fight the old bosses again but get there exclusive weapons and buggies eggs to hatch into buggies but there not cheap to make but basically it’s a loop hole for bringing back old bosses in there glory by making it post game and the infected broodmother buggy is very unique in its buggy form it shoots bombs but can’t glide.
