When I was a kid, Ghostfish was a fakemon on the same level as Pikablu and Mewthree.
Just on a whim, I googled 'ghostfish pokemon' and noticed there were zero results.
Normally I'd chalk this up to "Well it must have only been a thing at my old school" but I distinctly remember people joking about Ghostfish in late-elementary school all the way up to early-high school, and I changed cities when I graduated from elementary school and started high school. It's really bizarre that people would talk about this thing in two different cities (admittedly in the same state), but there would be nothing about it online.

Does anyone here remember Ghostfish?
I don't remember any details about it considering it's been roughly 20 years since then, but it just popped back into my mind and now I'm curious.

Pic mostly unrelated: It's a Mario enemy.
