I did a little bit of research and I suspect it to be a Korean meme about a shitty/creepy chikorita plush that never made waves outside of the country. If moonkomoonko happens to be a Korean user, it would make sense that they might not have a sufficient level of English to ask for editorship or reply to us (original entry creator account has deactivated). If that is just the case, then the meme's presence here is entirely valid and I will look into it further to write the best entry i can, but I don't speak a word of korean and I don't think the other active mods do either.
In the meantime I cannot advocate for any action to be taken against moonkomoonko. Not unless we find actual reason to believe there was ill will involved.
