Merging Irritable ghost and Pink pages

[tentechBiolognostic]

In actual page text, we'd omit the disambiguators. So we'd just be talking about 'Pink' and 'Pink', and that'd be terribly confusing lol

Relevant quote from here:

@Remex_Remige

This goes beyond the name on top of the page. That is the name that the wiki will use to refer to the minigame inside the article, including other articles that reference it. The parenthesis are omitted in this case.
