Help How to get katakana reading practice?

I recently learned hiragana very quickly simply by reading these stories out loud which are written purely in hiragana Japanese Stories
I found that simply reading it out loud non-stop allowed me to learn all hiragana in a few days. I'm very keen to do the same with katakana but I'm having trouble finding any pure katakana script. Is there any reading material that is purely katakana anywhere?

And yes I know that long texts wouldn't normally be written in just katakana in Japan, this is for the sake of my reading practice

Copy whatever passage you want to read in katakana and paste it here
I used to copy-paste random Japanese wikipedia articles back in the day for my kana practice.

Robots speak in Katakana. Read something with lots of robots in it.

I think it's also hard to find pure katakana texts because if I remember correctly Katakana is normally only used for words they've taken from other languages such as bread being taken from the french word Pan and also the part time job being taken from German. So it's unnatural to find pure katakana texts I think. Could be wrong though, this is just my assumption.
