Switch [BUG] low fps in skull cavern caused by pepper rex

[lu18ca04]

yesterday i played split screen with a friend and we visited the skull cavern. We saw a pepper rex and when he breathed fire the game lost a few fps. Later we found a prehistoric floor and tried to beat the level but it was not possible because the game was lagging a lot when we fought against them. game version:1.5.4.1
Edit: I asked on reddit and it seems like xbox,playstation and mobile have the same problem.

I have the same problem.
Split/Screen. As soon as pepper rex breathes fire we have massive frame drops. Close to unplayable.
